Use the Salpeter mass function for stars to estimate the fraction of stars with masses between 5 and 100 solar masses. Assume stars range in mass from 0.07 to 100 solar masses. What is the fraction of all stars more massive than the sun?

Step 1
To do this, we need to integrate the Salpeter mass function over the mass range of 0.07 to 100 solar masses. The Salpeter mass function is given by: ξ(M) = ξ0 * M^(-α) where ξ(M) is the number density of stars with mass M, ξ0 is a normalization constant, and α Show more…
