Spectroscopy of candidate YSOs in Serpens

We have completed an optical spectroscopic survey of a sample of candidate young stars in the Serpens Main star-forming region selected from deep B, V, and R band images. While...我们已针对从深场B、V、R波段成像数据中筛选得到的蛇夫座主星形成区（Serpens Main star-forming region）候选年轻恒星样本，完成了一项光学光谱巡天研究。然而……
