Bibcode: 1986A&A...161...31N Altcode: Based on high-resolution granulation photographs obtained on the Stratoscope-I flight of August 17, 1959, a morphological study of the evolution of exploding granule expansion rate is found to increase linearly with size, with 1.7-3.2 km/s for granules with maximum attained diameters of 3-5.5 arcsec. Granules with the shortest axis of 2.2 arcsec are seen to develop the characteristic ring-like appearance with a round darkening in the center, and the exploding granules are found to occupy roughly 2.5 percent of the solar surface at any moment. In a study of the typical exploding granule, the size and intensity depression of the central darkening are shown to evolve with granule expansion in the rapidly growing phase, and the intensity drop is found to reach 25 percent of the granule brightness.

Bibcode: 1983A&A...117..277N Altcode: Actual profiles have for the first time been obtained of the high excitation C I 5052-A line from individual granules and intergranular regions, and Doppler shifts between the two regions. Although these structures are only partially resolved, due to smearing by instrumental and atmospheric stray light, a simple correction for this effect points to convective velocities of a few kilometers/sec in the photospheric layers where the 'white light' granulation is observed. It is not yet possible, however, to determine the absolute values of the upward and downward velocities in the graduation and the possible influence of the five-min oscillation.

The evolutionary pattern of exploding granules is summarized schematically, and several characteristic features are derived from a study of seven such granules. The exploding-granule phenomenon is interpreted qualitatively in terms of cooling at the photospheric level and the subsequent sinking of cold matter at the center of a granule due to loss of buoyancy Title: Book review Authors: Namba, O.

Bibcode: 1969SoPh....7..167N Altcode: Some properties of the photospheric granulation near the centre of the quiet sun have been investigated on the basis of two high-definition Stratoscope photographs. We obtain (1) a number density of 54 granules per 10″ × 10″, (2) a total number of granules on the whole surface of 6.3 × 106, (3) a mean cell diameter of 1″.5 or 1100 km and a mean granule diameter of 1″.2 or 850 km, the difference of 250 km being ascribed to the mean width of the dark intergranular lanes, (4) frequency distributions of cell diameters and granule diameters (Figures 1 and 2), and (5) an isophotal map in relative intensity (Figure 3). In general, larger granules are brighter than smaller granules (Figure 4). Cross-section profiles are shown for some granules and intergranular lanes (Figures 5 and 6). These quantities have not yet been corrected for the finite resolution of the telescope.

Bibcode: 1959PASJ...11...50N Altcode: The a-particles carried from the corona by some hypothetical "hot streams" may be a source of the high excitation of the He II spectrum in the low-temperature chromosphere. Significance of the far ultraviolet radiation, also carried by the hot streams, is suggested. Title: On the Excitation of Neutral Oxygen in toe Solar Chromosphere Authors: Namba, O. Bibcode: 1954PASJ....6...87N Altcode: The high excitation of neutral oxygen observed in the flash spectrum is attributed to the resonance fluorescence with the hydrogen radiation field in the chromosphere: Owing to the coincidence of ionization potentials for these two elements, the strong Lyman continuous radiation would ionize oxygen atoms highly and overpopulate the excited levels through the subsequent recombination process, giving the ionization and excitation temperatures comparable with those for hydrogen. ` he resonance excitation of oxygen with Lyman- line emission is also considered. A brief estimation shows that, in the chromosphere, thin effect may be less important than that of Lyman continuum.
