We present preliminary results from 50 smoothed particle hydrodynamics (SPH) simulations of weakly turbulent cores of molecular gas with turbulent Mach number 0.2, radius 0.13 pc and mass 5 M☉. We use the SEREN code which includes self-gravity and sink particles to model protostars. We use a barotropic equation of state and do not include magnetic fields or radiative transfer due to computational limitations.
The cores collapse and fragment, forming protostars; we examine their mass function and binary properties. Each core produces approximately 4 stars with a core mass to star mass efficiency of 25%. The system multiplicity is approximately 40%; cores may produce more than one multiple system.
