Question

Quizplus · Accepted Answer

According to Figure 17-15a, A0 V stars have masses between 2.5 and 3.5 solar masses. Additionally, Figure 17-22 shows that stars with a surface temperature of 10,000 K have a mass between 2 and 4 solar masses. Therefore, based on these two figures, the best estimate for Vega's mass is between 2.0 and 3.0 solar masses, which is option D.
