The distribution function can then be used to construct the mass distribution (the histogram of stellar masses) of a population of stars.

The IMF can be inferred from the present day stellar luminosity function by using the stellar mass-luminosity relation together with a model of how the star formation rate varies with time.

In particular, the classical assumption of a single IMF covering the whole substellar and stellar mass range is being questioned in favor of a two-component IMF to account for possible different formation modes of substellar objects.

For instance the astrophysical background from stellar mass binary black-hole mergers is expected to be a key source of the stochastic background for the current generation of ground based gravitational-wave detectors.

In this band the most likely source of the stochastic background will be an astrophysical background from binary neutron-star and stellar mass binary black-hole mergers.

72% of the stellar mass is located in the outer disk of the galaxy, and 20% is found in the bar.

The bulge adds 5% of the stellar mass, and its star population is generally older.
