EVOLUTION OF A SOLAR
... The Life and Death of a Sun-like Star These notes describe the evolutionary path taken by a Sun-like star, one with an initial mass comparable to the Sun’s mass. Stars can be thought of as a series of nested shells, surrounding a core. The core is more dense, hotter, and at higher pressure than the ...
