WebJan 14, 2024 · The photosphere is the outer shell of the Sun from where the visible light is radiated. You can observe so-called granules, areas of about 1000 km in diameter, where hot gas from inside the Sun rises to reach the surface of the Sun. As the gas cools down, the gas slides down again into the Sun's interior. The brighter regions indicate hot ... WebThe granulation is basically a convective phenomenon, each granule and its surrounding dark material representing a single convection cell. A useful feature of this volume is an extended discussion of the theory of convection, emphasizing astrophysical convection but including where relevant the theory and results of laboratory experiments.
