Optical Spectroscopy of Candidates of Young Stellar Objects in NGC 1333


We carried out low-resolution optical spectroscopy of 14 low-luminosity young stellar object (YSO) candidates in the NGC 1333 cluster. These objects were previously identified by the near-infrared imaging survey. Eleven objects were confirmed as YSOs by the Hα line emission. Strengths of the Hα emission are correlated with the near-infrared excesses of the… (More)
