... In other words, how hot, how luminous and which stages a star will go through and eventually become (its life span) is dependent upon the star's original mass at the time of formation. "The Hertzsprung -Russell (H-R) Diagram is a graph that plots stars color (spectral type or surface temperature) vs ...

... Schönberg and Chandrasekhar determined the constant to be 0.37, and if the envelope has a solar composition and the core consists of helium we have that µenv = 0.6 and µc = 1, which gives us Mc /M ≤ 0.13. As the core mass exceeds this value the core contracts rapidly. For stars larger than 2M the ...
