Spectroscopic Observations of Emission-Line Stars in the Orion. I. ORI OB 1b Region
Abstract
The results of spectroscopic observations for 34 emission-line stars (ELS's) detected in the Orion Belt (Ori OB 1b) region are presented. Spectral classification and measurements of the Hα and Hβ emission intensities are carried out and their spectral behaviors are compared with those of classical and weak-emission-line T Tauri stars. It is then found that the observed ELS's are highly probably T Tauri-type stars in most cases.
