Question
What is the luminosity (in solar luminosities) of $(\mathrm{a})$ a $0.5 \mathrm{M}_{\odot}$ and $(\mathrm{b})$ a $5.0 \mathrm{M}_{\odot}$ star?
Step 1
For stars with masses between 0.1 and 2 solar masses, α is approximately 4. For stars with masses between 2 and 20 solar masses, α is approximately 3.5. Now, let's calculate the luminosities for the given stars: a) For a 0.5 M⊙ star: Since the mass is between Show more…
