A Search for T Tauri Stars toward Nearby, Dense Cores

Asuka Ota, Koji Sugitani, Makoto Watanabe

We have searched 14 dense cores, 11 of which have literature distances of 150-350 pc, for T Tauri stars by using the Wide Field Grism Spectrograph 2 on the University of Hawaii 2.2 m telescope. As a result, we detected 50 Hα emission stars including 24 newly found objects. Twelve out of these 50 stars have a distance of ~190-370 pc, and 16 of them are within a distance of ~460 pc. Seven of these 16 objects are newly found Hα emission stars and would serve as new good targets for studying protoplanetary disks and young exoplanets.
