Abstract
Abstract We carried out near-infrared spectroscopic observations of 23 very low-luminosity young stellar object (YSO) candidates and 5 of their companions in Heiles Cloud 2, one of the densest parts of the Taurus molecular cloud. Twelve objects were confirmed to be YSOs by the $\mathrm{B}\gamma$ feature. The effective temperatures of the YSOs and of the companions are estimated from the 2.26-${\mu \mathrm {m}}$ feature, the 2.21-${\mu \mathrm {m}}$ feature, and the $\mathrm{H}_{2}\mathrm{O}$ band strengths. Detailed comparisons of our photometric and spectroscopic observations with evolutionary tracks on the HR diagram suggest some objects to be very low-mass YSOs.
