Is There a Relationship Between the Mass of a Main-Sequence

question 134

Multiple Choice

Is there a relationship between the mass of a main-sequence star and its luminosity?

• A) No. Large masses can have low luminosities and vice versa.
• B) Yes. Mass and luminosity are related linearly: A star twice as massive has twice the luminosity.
• C) Yes. The mass and luminosity are related, but not linearly: A star twice as massive has more than twice the luminosity.
• D) Yes, but surprisingly there is an anticorrelation: Larger masses have smaller luminosities.
