历史在继续：罗马诺之星的百年研究
The History Goes On: Century Long Study of Romano's Star
摘要：
GR 290（M 33 V0532 =罗马诺星）是M33星系中一颗独特的变星，它同时显示出亮蓝变星（LBV）的典型变化和富氮沃尔夫-拉叶星（WR）的典型物理参数。到目前为止，GR 290是第一个被确定为后LBV恒星的天体。在本文中，我们概述了取得的主要成果，从广泛的光度和光谱观测的恒星：其风的结构和化学成分及其随时间的演变，系统增加的热光度在光极大值，星周环境。这些结果表明，罗马诺星的当前状态构成了超大质量恒星演化路径的基本环节。
英文摘要：
GR 290 (M 33 V0532 = Romano's Star) is a unique variable star in the M33 galaxy, which simultaneously displays variability typical for luminous blue variable (LBV) stars and physical parameters typical for nitrogen-rich Wolf-Rayet (WR) stars (WN). As of now, GR 290 is the first object which is confidently classified as a post-LBV star. In this paper, we outline the main results achieved from extensive photometric and spectroscopic observations of the star: the structure and chemical composition of its wind and its evolution over time, the systematic increase of the bolometric luminosity during the light maxima, the circumstellar environment. These results show that the current state of Romano's Star constitutes a fundamental link in the evolutionary path of very massive stars.
