| Outline of Final Research Achievements |
We have studied star formation in the several environments, i.e., different levels of turbulence and magnetic fields. We have performed large-scale numerical simulations with adaptive mesh refinement (AMR), which allows us to obtain a local high resolution. Several models were investigated: cloud interaction (cloud-cloud collision), protostar formation starting from a cloud scale, and circumbinary structure.
The results of the numerical simulations were compared with the recent high-resolution observation with ALMA and the 45 m telescope at Nobeyama Radio Observatory. By comparison between the numerical simulations and the observation, we discussed several phenomena in the molecular cloud Cyg OB 7, the high-density molecular cloud core MC27, and protobinary stars L1551 NE.
