New hydrodynamical simulations of star cluster formation

I will present results from my latest star cluster formation calculation which is due to be completed at the end of June. Earlier calculations modelled the collapse of 50 solar-mass molecular clouds to form small stellar clusters containing a few dozens of stars and brown dwarfs. They produced a variety of predictions for the properties of stars and brown dwarfs which are currently being tested by observations. The new calculation models a cloud 10 times larger and is expected to form around 1000 stars and brown dwarfs by the time it is completed. This calculation will provide much better statistics for the IMF, binarity, circumstellar disc and other properties than the earlier calculations. It will also be the first hydrodynamical calculation that produces a star cluster containing stars ranging from the lowest-mass brown dwarf through to stars of ~10 solar masses and will therefore be more comparable to clusters such as IC348 and the Orion Trapezium Cluster than the previous smaller calculations.
