On the basis of the Hertzsprung-Russell diagram (Figure 17-15a) and the mass-luminosity relationship for main-sequence stars (Figure 17-22), which of the following main-sequence stars have the greatest mass?

Question

Quizplus · Accepted Answer

On the Hertzsprung-Russell diagram, O-type stars are located in the upper left corner, indicating they are very hot and very luminous. The mass-luminosity relationship for main-sequence stars shows that more massive stars have higher luminosities. Therefore, O-type stars have the greatest mass among the main-sequence stars.
