Massive Stars in the Galaxies of the Local Group
Philip Massey
TL;DR
This review discusses how Local Group galaxies serve as natural laboratories for testing and understanding the evolution of massive stars, highlighting recent progress and ongoing challenges.
Contribution
It provides a summary of current knowledge on massive star evolution and discusses recent advances in identifying different massive star types in Local Group galaxies.
Findings
Improved identification of massive star types in Local Group galaxies
Enhanced understanding of massive star evolutionary pathways
Recognition of ongoing challenges in massive star classification
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.
