碩士 === 國立中央大學 === 天文研究所 === 94 === We report a pilot study to identify emission-line stars by use of the image database of the hydrogen-alpha survey by the United Kingdom Schmidt Telescope. The Lupus dark clouds are among the nearest star-forming regions. We analyzed a 30’ x 30’ field of the UK Schmidt Hα images centered around the 2 Herbig Ae stars of the Lupus 3 cloud. A list of 46 candidate T Tauri stars have been identified, among which 22 are new identifications. Seven out of these 22 Hα stars have 2MASS infrared colors consistent with being classical T Tauri stars. Once the candidates are spectroscopically confirmed, these stars will add to the young stellar sample in the region to study the star formation process in the molecular cloud.
