Scientific paper

We performed high-resolution simulations using a nested grid in order to investigate binary formation. The simulations show a nearly equilibrium molecular cloud core fragments when the cloud rotates slowly, and the fragments evolve to proto-binaries. The conditions of the fragmentation is satisfied by many observed molecular cloud cores. The binary separation is also consistent with observations. The major mode of the fragmentation is satellite type fragmentation, in which a massive circumstellar disk fragments.
