How hot is the convective zone
In main sequence stars more than 1.3 times the mass of the Sun, the high core temperature causes nuclear fusion of hydrogen into helium to occur predominantly via the carbon-nitrogen-oxygen (CNO) cycle instead of the less temperature-sensitive proton–proton chain. The high temperature gradient in the core region forms a convection zone that slowly mixes the hydrogen fuel with the helium product. The core convection zone of these stars is overlaid by a radiation zone that is in t… WebThe solar atmosphere is made up of: the photosphere (the visible surface of the Sun), the chromosphere (an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C), a …
