Las Cholas de Estrellas
This is a HR digram and Rigel is circled in purple.
Rigel is made up of about 75% hydrogen and 24% helium. While Rigel is in the main sequence it will burn hydrogen to helium in its core. It has a shell of expelled gas around it. Scientist think that the shell of gas around Rigel is there because of its pulsations, stellar wind, or both. The basic parts of Rigel are the Core, Radiative zone, Convective zone, Filament, and the Chromosphere.
Rigel is not expanding or contracting in the main sequence because the pressure on the outside of the star is less than the pressure on the inside of the star. If the pressure on the outside of the star was more than the pressure on the inside of the star than the star will either collapse or expand.
The energy generation from a star in the main sequence is caused by the convective zone and the radiative zone. The two zones push on each other making the core heat up. The heat in the core moves outward toward space.

This is a picture of the basic parts of a star.
