Abstract The star-forming galaxies of the Local Group act as our laboratories for testing massive star evolutionary models. In this review, I briefly summarize what we believe we know about massive star evolution, and the connection between OB stars, Luminous Blue Variables, yellow supergiants, red supergiants, and Wolf–Rayet stars. The difficulties and recent successes in identifying these various types of massive stars in the neighboring galaxies of the Local Group will be discussed.

本地群星系中的大质量恒星

摘要 本星系群的恒星形成星系是我们测试大质量恒星演化模型的实验室。在这篇综述中，我简要总结了我们认为我们对大质量恒星演化的了解，以及 OB 星、发光蓝变星、黄超巨星、红超巨星和沃尔夫-拉叶星之间的联系。将讨论在本星系群的邻近星系中识别这些不同类型大质量恒星的困难和最近的成功。
