Webstar may become a red or a blue giant. This may depend on small changes in the proﬁle of chemical composition, e.g. on the details of variation of hydrogen abundance with mass fraction, X(Mr). In fact, in many cases a star with exactly the same hydrogen proﬁle, X(Mr), may be either a red giant, or a blue giant, depending on its previous ... WebThe evolution time from the red giant region to maximum T eff is about 10 5 years, during which time the radius decreases from its maximum value to about 0.1 R ⊙ (Fig. 11).
