标题： SALT spectroscopy of evolved massive stars

摘要： 使用南非大型望远镜（SALT）对由斯皮策空间望远镜和广域红外巡天探测器（WISE）探测到的中期红外星云中心恒星进行长缝光谱观测，发现了大量的候选明亮蓝变星（cLBVs）和其他罕见的演化大质量恒星。 随着SALT光纤馈送高分辨率光栅光谱仪（HRS）的近期投入使用，这些有趣天体的研究出现了一个新的视角。 利用HRS，我们获得了十几颗新识别的大质量恒星的光谱。 展示了最近确认的cLBV Hen 3-729的一些结果。 显示英文摘要

摘要： Long-slit spectroscopy with the Southern African Large Telescope (SALT) of central stars of mid-infrared nebulae detected with the Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE) led to the discovery of numerous candidate luminous blue variables (cLBVs) and other rare evolved massive stars. With the recent advent of the SALT fibre-fed high-resolution echelle spectrograph (HRS), a new perspective for the study of these interesting objects is appeared. Using the HRS we obtained spectra of a dozen newly identified massive stars. Some results on the recently identified cLBV Hen 3-729 are presented.
