A main sequence star with a mass of three times the Sun will evolve through a series of stages. Which of the following sequences of stages could correctly represent the path of the evolution of this star?
A. A→B→D→E→G
B. C→B→D→E→G
C. A→B→D→E→F
D. C→B→D→E→G
参考答案: A
本题详细解析: Explanation:
Since the mass of the star is greater than the Sun, its luminosity should be higher. Therefore, its position on the main sequence should be A instead of C, where C represents the Sun. Moreover, the last stage of the evolution should be white dwarf which is labelled as G.
