The photospheric network

Solar Physics, 1968
Spectroheliograms, obtained in certain Fraunhofer lines with the 82-cm solar image at the Kitt Peak National Observatory, show a bright photospheric network having the following properties: (1) It resembles, but does not coincide with, the chromospheric network, the structure of the photospheric network being finer and more delicate than the ...

Solar Photosphere

2020
Abstract The Sun is a G2V star with an effective temperature of 5780 K. As the nearest star to Earth and the biggest object in the solar system, it serves as a reference for fundamental astronomical parameters such as stellar mass, luminosity, and elemental abundances. It also serves as a plasma physics laboratory.

The Photosphere of the Sun

1959
An empirical model of the photosphere rests on observations of: (1) the solar constant—which fixes the temperature scale, (2) limb darkening—from which the variation of temperature with depth throughout the atmosphere is determined, and (3) the energy distribution—which, together with limb darkening, reveals the opacity at each depth and for each ...
