A large-scale search for T Tauri stars toward star cluster forming regions

我们利用安装在夏威夷大学2.2米望远镜上的广场格栅光谱仪2号(WFGS2)对几个星团形成区(如IC1396、CEP B)进行了大规模的TTauri星的搜寻，以考察它们的恒星形成历史。我们还对年轻的星系团形成区(蛇云核、蛇南)进行了近红外偏振和(或)CO(J=3-2)观测，认为原恒星的磁场和湍流在星系团的形成中起着重要的作用。

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.
