Bibcode: 1979stcl.book.....P Altcode: The origins, evolution and fates of the various stars and star clusters in the Galaxy are surveyed. The structure and composition of the Galaxy is discussed, and the Hyades cluster is presented as a model for other star clusters located further from the sun. Consideration is given to the chemical compositions of stars in various stages of evolution, and to the physics of this development. The pre-main-sequence, main sequence and post-main-sequence stages in stellar evolution as determined from observations of clusters are then examined, with attention given to supergiants, Cepheid variables and red giants. The characteristics of the oldest open clusters are discussed, and the relationship between the open clusters and the structure of the Galaxy to which they belong are considered. Globular clusters are then introduced, including metal-rich globular clusters and red and short-period variable stars contained within them, and the final stages of the lives of stars of various masses are indicated. The development of the poorest possible star cluster, the binary star, is also discussed, and a complete atlas of stars, nebulae and clusters to a magnitude of 6.05 is presented.

G.; Payne-Gaposchkin, C. Bibcode: 1979EExSc...3..161K Altcode: A summary of the positions, infrared photometry, spectral classifications, maser properties and indications of variability is provided for the 96 sources in the Two-Micron Sky Survey for which (I'-K) is at least about 6 mag. The majority of the sources are long-period Mira variables of spectral class later than M6, or C; a few are distant reddened supergiants. Both the frequency of detections of maser emission and photometry of these stars in the range 2-20 microns provide evidence that most of them have well-developed circumstellar envelopes which must be responsible at least in part for their extreme redness at wavelengths less than or about equal to 2 microns.

Authors: Payne-Gaposchkin, C. H. Bibcode: 1977AJ.....82..665P Altcode: Knowledge gained about novae over the last 50 years is reviewed. The realization that a thermonuclear runaway is the source of energy for a nova outburst is discussed along with the spectral development of several novae, the geometry of nova outbursts, postnova development, and the binary nature of novae. Properties of cataclysmic binaries are summarized, with specific attention given to periods, component stars, symbiotic variables, and the lack of correlations between orbital period and outburst range, outburst cycle, and brightness variations. Individual novae considered in some detail include GK Persei, RR Pictoris, V603 Aquilae, CP Puppis, and T Coronae Borealis. Title: Past and Future Novae Authors: Payne-Gaposchkin, C.

Bibcode: 1976SAOSR.370.....P Altcode: 1976STIN...7623109P Of the 5600 objects in the infrared catalogue of Neugebauer and Leighton, more than 70% have been identified with optically observed stars of late spectrum, and more than 25% are known variable stars (Mira, semiregular, and slow irregular variables in about equal numbers). The variations of color with phase have been studied for 166 Mira stars (spectrum M, S, and C) for which infrared observations and simultaneous visual estimates are available. The variations of color with phase, and of infrared magnitude with phase, are related to maximal spectrum and to period. A recalibration of the relation between effective temperature and the water-cell index of Pettit and Nicholson leads to a radius variation that differs significantly from the one that they obtained. We derive a relation between infrared color and surface brightness for non-variable giant stars; supergiants and Mira Ceti deviate from this relation, even when allowance is made for the dependence of radius on wavelength. We conclude that the photometric determination of radius variations is unrealiable, and the scale of effective temperatures highly uncertain.

Bibcode: 1975MSRSL...9..419P Altcode: 1975apes.conf..419P; 1975assp.conf..419P Variations of color with phase are investigated for 166 M, S, and C Mira-type stars for which IR observations and simultaneous estimates of visual magnitudes are available. The stars are grouped by maximal spectrum and period in order to study the variation with phase of the three color indices (I'-K), (V-K), and (V-I'). Brightness variations of long-period variables are analyzed, a relation between IR color and surface brightness is derived for nonvariable giants, and the relation between effective temperature and watercell absorption index obtained by Pettit and Nicholson (1933) is recalibrated using stellar angular diameters and K magnitudes. It is found that supergiants and Mira Ceti deviate from the relation for giants, that the recalibration leads to a radius variation significantly different from that determined by Pettit and Nicholson, and that there is no simple relationship between surface brightness or effective temperature and spectral type. It is concluded that the temperature scale for M stars derived by Dyck et al. (1974) is highly tentative and that photometric determinations of radius variations are unreliable.

Data cover: (1) ages of color magnitude array clusters, luminosities of Wolf-Rayet stars, and periods of Cepheids, (2) the use of period changes for gallactic and Magellanic Cepheids to test time scales derived for Cepheids, (3) possible differences of composition, and (4) differences and compatability of period-amplitude and period-frequency relations. Data suggest that the observed differences between the three systems can be interpreted in terms of differences in the timetable of star formation, without the need to invoke initial differences of composition. Title: Intrinsic ultraviolet colors from OAO-2 Celescope observations for stars on the main sequence Authors: Haramundanis, K.; Payne-Gaposchkin, C.

Relationships between intrinsic ultraviolet color, (B- v)o, and spectral class are presented for main-sequence stars from B 0 to G 3. A brief description of the Celescope and its calibration is included, and a comparison of the determined colors is made with theoretical colors.

Authors: Payne-Gaposchkin, Cecilia Bibcode: 1963ApJ...138..320P Altcode: The spectrum of R Coronae Borealis at maximum is that of a supergiant carbon star of spectral class equivalent to F7. As the star drops to minimum, veiling of the absorption spectrum is followed by the appearance of a very rich, bright4ined spectrum with relatively sharp lines, which fades exponentially, and also by the appearance of several strong, broad, bright lines, which persist with little change for some time and later fade abruptly. The average conditions in the layers that produce the rich, bright-lined spectrum correspond to 0 = 1.02, log P = -2.0, somewhat lower in temperature than the photosphere and at much lower electron pressure. The broad, bright-lined spectrum shows the H and K lines, the D lines, and a line at 3889 A which is ascribed to He I. The changes during the minimum are ascribed to a slow contraction of the envelope, leading to increased density and the deposition of carbon black, which is responsible for the large changes in brightness and for the reddening of the star's light. The rich, bright-lined spectrum is neither obscured nor reddened and is ascribed to an expanding chromosphere that fades progressively. The broad, bright-lined spectrum is ascribed to material which is ejected with high velocity in connection with the initial contraction of the envelope and is collisionally excited when it interacts with a circumstellar cloud. The other cool stars of R Coronae class behave in a similar manner, and their rate of variation is shown to be related to their photospheric temperatures.

C.; Payne-Gaposchkin, Cecilia Bibcode: 1951MNRAS.111..506M Altcode: It is assumed that the stars which constitute the spiral arms of a galaxy are formed from the disintegration of a bar of material which, at the moment of disintegration, is rotating like a rigid body. After their formation, the stars move under the Newtonian inverse-square-law attraction of a point-mass nucleus located at the centre of the bar. Tiie stars move in elliptical orbits having their perigalactica or apogalactica on the initial position of the bar. The spiral arms are not orbits, but are curves defined by the "present positions" of the stars. The velocities to be expected are also found. The method of solution of the relevant equations is a graphical one. The principal conclusions are : (i) the shape of a galaxy alone does not determine its mass and the age of its arms, but shape, together with velocity of the stars in the arms, does so; (ii) arms may " lead" for parts of their extent and" trail " for the remainder; (iii) a fit can be obtained for the shapes of M5I, M8I and M83 and for both shape and velocity of the outer parts of M the mass of M33 and the age of its arms are also found; (iv) the shape, mass and age of the Galaxy can be predicted and an explanation obtained of the ` leading" arm in the Cygnus direction suggested by radio observations.

The behavior of the "red component" and the "blue component" is analyzed photometrically and is shown to be closely related to the remarkable spectroscopic variations of the star. The photographic light-curve of AX Persei is shown to bear a strong resemblance to that of Z Andromedae, and the similarity of the spectroscopic phenomena in the two systems suggests that they have a close physical resemblance Title: James H.

The principal con- clusions relative to this unusual system are: (1) there is a regular intrinsic variation in a period of 517 days, and this may be ascribed to variation of the blue component with a range of 0.6 mag.; (2) the photometric elements of the eclipsing pair, derived at the times of the maximum, mean, and minimum of the long- period curve, are sensibly similar, except in the ratios of surface brightness; and (3) the relative lumi- nosities of the components, derived from the, long-period variations and from the photometric elements, are in agreement Title: «Variable stars» Authors: Payne-Gaposchkin, C.; Gaposchkin, S.

Authors: Payne Gaposchkin, Cecilia; Gaposchkin, Sergei Bibcode: 1945ApJ...101...56P Altcode: 1945HarRe.270....1P The theory of thick atmospheres, developed by Kosirev and by Chandrasekhar, is applied to the in- vestigation of the distribution of intensity over the stellar disk, as functions of temperature, wave length, and the structure of the atmosphere. Intensities are tabulated over the physically interesting range. The intensities are used in computing the forms of a number of typical eclipses, with ratios of radii 0.4, 1.0, and 2.0, and with ratios of luminosities 10.0 and 1.0, both central and partial. The theoretical curves are applied, for ifiustration, to the light-curves of SX Cassiopeiae, U Cephei, RX Cassiopeiae, AR Monocerotis, ER Orionis, V 444 Cygni, and Aurigae. The effect of the theory on stellar diameters measured with the interferometer is evaluated. For all the cases discussed, application `of the theory leads to appreciable modification of previous results. I. GENERA Title: The Eclipsing Star AR Monocerotis. Authors: Payne Gaposchkin, Cecilia Bibcode: 1944ApJ...100..251P Altcode: 1944HarRe.267....1P The eclipsing star AR Monocerotis, with a period of 21.208 days, has a light-curve of fi Lyrae form, as determined from 1441 estimates on Harvard plates. Relative dimensions were obtained from this photo- graphic light-curve and from a rediscussion oT the visual light-curves of Florja and Lause. The relative mean radii of the K and the unknown components are 0.332 and 0.086 in photographic light, 0.265 and 0.133 in visual light. The star thus shares with SX and RX Cassiopeiae the peculiarity of possessing di- mensions that apparently differ with wave length. Photographic and visual light-curves give values of the inclination of the orbit as 76~5° and 82.5°. On the basis of the mass function determined by Sahade and Cesco and an adopted mass ratio (?/K) of ~, radii for the K and the unknown star are found to be 22.7 0 and 5.9 0 in photographic and 18.1 0 and 9.0 0 in visual light. With assumed temperatures of 4ç)()()° and 60000 for the two stars, absolute visual magnitudes of 0.52 and 0.96 are deduced from the photographic light-curve and 1.01 and 0.06 from the visual light-curve. The photographic light-curve is considerably the better determined, and conclusions drawn from it are regarded as of the greater weight Title: The Eclipsing Star BD Virginis. Authors: Payne Gaposchkin, Cecilia Bibcode: 1944ApJ...100..186P Altcode: 1944HarRe.263....1P The eclipsing star BD Virginis is studied on the basis of 773 Harvard plates. It is apparently a normal Algol star. The range is from 1O'~25 to 11m45. A grazing eclipse is adopted, the inclination of the orbit being 77°. If the earlier star is of spectral class A2, the other is an F or G star, a typical subgiant. In period, light-curve, dimensions, and masses the system resembles that of Algol Title: Notes on Five Eclipsing Stars Authors: Payne-Gaposchkin, Cecilia Bibcode: 1943BHarO.917....7P Altcode: No abstract at ADS Title: Problems of Stellar Evolution Authors: Payne-Gaposchkin, Cecilia Bibcode: 1943S&T.....2....5P Altcode: No abstract at ADS Title: The variables of RV Tauri type Authors: Payne-Gaposchkin, Cecilia; Brenton, Virginia K.; Gaposchkin, Sergei Bibcode: 1943AnHar.113....1P Altcode: 1943QB4.H33v113n1..

Authors: Payne-Gaposchkin, Cecilia Bibcode: 1939ApJ....90..321P Altcode: 1939HarRe.181....1P The red indices of nearly five thousand stars, in the Selected Areas at _600, for which spectral classifications have been made at Potsdam, furnish material for a dis- cussion of spectrum and color in relation to galactic structure. The Potsdam sysl~em of spectral classification differs appreciably from the Henry Draper system. The accidental errors of both systems have been evaluated as functions of spectral class and apparent magnitude. The Harvard system does not contain as many subdivisions as the accidental error of classification warrants; the Potsdam sys- tem, on the other hand, is too finely subdivided. The systematic differences of classifi- cation are functions both of apparent and of absolute magnitude. Of the twelve Selected Areas studied, six are in galactic latithde greater than 20°, where obscuration should, on the average, be negligible. For these six areas, containing eleven hundred stars, the colors are normal throughout the spectral sequence. The high-latitude areas can therefore be used as standards of normal color for comparison with other areas. The six low-latitude areas differ in spectral makeup and in degree of obscuration. Selected Area 193 (Carina) shows extremely little reddening, and the frequency of blue stars is the greatest in this area: the negative density gradients that have been derived for blue stars in this part of the sky are partly a result of systematic errors of spectral classification. The other five areas, while differing in spectral makeup, show similar color excesses, not very different from those found by other investigators in other parts of the sky. The principal results of the analysis is the stress that it lays on the importance of standardizing both spectral classification and magnitude systems. Otherwise, accurate and consistent conclusions on galactic structure cannot be drawn from studies of colors and spectra of faint stars Title: Spectrophotometry of Nova Herculis in its Intermediate Stages.

Bibcode: 1927Natur.119..925H Altcode: IN NATURE (May 14, p. 707) Dr. E. A. Baker discusses the calibration curves of photographic plates. The curves he gives certainly show a good agreement in sensitivity between the different batches of plates used under his conditions of standardisation. Concerning the reference to Harvard results (Harvard Circular 302), it may be of interest to note several points not fully discussed in the original paper on spectrophotometric method.

Bibcode: 1924Natur.113..783P Altcode: THE application of the theory of ionisation to stellar spectra by Saha and others has led to estimates of the temperature of the reversing layers of stars. It is shown by Fowler and Milne (Mon. Not. R.A.S., 83, 7, 415) that the effective temperature at a given point in the stellar sequence may be deduced, on certain assumptions, from the knowledge that a line of known series relations there reaches its maximum intensity. For stars of type earlier than Ao the lines available for such estimates are those associated with Si+++, He, and C+. The intensities of these lines have recently been measured on a number of objective prism spectra at the Harvard College Observatory. Title: B-Stars Authors: Payne, Cecilia H.
