Turbulent Fragmentation Reproduces Most Binary Statistics Plot showing the Companion Frequency vs. Log Mass [M]. Observations are plotted as black dots with error bars. There are very few companions at the low-mass end and a high number of companions at the high mass end. Starforge simulations are plotted as a green line. They are consistent with the data points. Illustrations of (a) Filament Fragmentation: Delta t~0.5 Myr, Delta L~0.01-0.25 pc (b) Core Fragmentation: 0.2 Myr, 0.01-0.1 pc. "Stellar binaries are bound from birth."

It can also create the correct distribution of binary stars with just turbulent fragmentation of the clouds of gas — meaning the stars have always formed a binary pair, they were not captured later.
STARFORGE also tells us that very small clouds will not form high-mass stars.
