If a star has a mass of 10 solar masses and a luminosity of 10,000 solar luminosities, how long is its lifetime? (The Sun's lifetime is 10 billion years.)

Question

Quizplus · Accepted Answer

There is a relationship between a star's mass, luminosity, and lifetime known as the mass-luminosity-lifetime relation. For a star with 10 solar masses and a luminosity of 10,000 solar luminosities, its lifetime can be estimated using this relation to be approximately 10 million years. Therefore, the correct answer is D.
