Research Abstract

We have carried out a search for T Tauri stars on a large scale toward a few cluster forming regions (e.g., IC1396, Cep B) with the Wide Field Grism Spectrograph 2 (WFGS2) mounted on the University of Hawaii 2.2-m telescope to examine their star formation histories. We also have conduced near-infrared polarimetry and/or CO (J=3-2) observations toward young cluster forming regions (Serpens Cloud Core, Serpens South), and suggested that the magnetic field and turbulence from protostars play an important role in cluster formation.
