The Formation Mechanism and Resulting Properties of Brown Dwarfs

Matthew R. Bate, Ian A. Bonnell, and Volker Bromm

Proceedings of `Brown Dwarfs', ed. E. L. Martin, in press. IAU Symposium 211 held in Hawaii, 20-24 May 2002


We present results from the most ambitious hydrodynamic star formation calculation performed to date. It follows the collapse and fragmentation of a large-scale turbulent molecular cloud to form dozens of stars and brown dwarfs. It resolves all fragmentation down to the opacity limit, binary stars with separations as small as $1$ AU, and circumstellar discs with radii down to $\approx 10$ AU. In this proceedings, we examine the formation mechanism of the brown dwarfs and compare the initial mass function and the properties of the brown dwarfs with observations.
