High-mass stars are a type of star that have a mass several times greater than that of the Sun. These stars are much more luminous and hotter than lower mass stars, and they also have shorter lifespans, typically ranging from a few million to a few hundred million years. Research on high-mass stars focuses on understanding their formation, evolution, and ultimate fate. Scientists study how these stars are formed in massive star-forming regions, how they interact with their surroundings, and how they evolve through different stages of stellar evolution, such as the main sequence, red giant phase, and supernova explosion. Additionally, research on high-mass stars also examines their impact on the surrounding environment, such as triggering the formation of new stars and enriching the interstellar medium with heavy elements through stellar winds and supernova explosions. Overall, studying high-mass stars provides valuable insights into the processes that govern the formation and evolution of stars and galaxies, as well as the role of massive stars in shaping the universe.
