# Salpeter function

The Salpeter function is a mathematical description of the way that newly-formed stars
are distributed by mass. Also referred to as the **initial mass function**,
the Salpeter function (the number of stars formed per unit mass range) is
proportional to *m*^{-2.35}, where *m* is the mass of
a star. It is named the Australian American astrophysicist Edwin Salpeter
(1924–2008).
