Recovers IMF down to 0.1 Msun ~1,700 stars (statistics!) Star formation efficiency (M/M) = 8% Plot of dN_star/dM_star vs M_star (M_sun), showing the distribution of stars by stellar mass. Stellar mass ranges from 0.01 to 100 solar masses. The standard IMF IMF (Chabrier 2005) and the Chabrier fit: -2.0±0.1 are shown. Data from STARFORGE is overplotted on these lines and is a good match, except on the very low end. The area between 0.01 and 0.1 solar masses is labeled "incomplete".

The story of a star's life from its birth, to how long it lives, to how it eventually dies, is determined by its mass. Star-forming nebulas tend to make stars with a distribution of masses known as the Initial Mass Function (IMF).
STARFORGE can reproduce the observed IMF down to about 0.1 times the mass of the Sun.
