Type B stars are a category of hot, massive stars that have surface temperatures ranging from about 10,000 to 30,000 degrees Celsius. They are typically blue in color and are much larger than our Sun, often having at least twice the mass. These stars are known for their strong stellar winds and rapid rotation, which can lead to the formation of nebulae around them. These stars are relatively short-lived, usually existing for only a few million years before exhausting their nuclear fuel. As they evolve, they may become supernovae or transform into neutron stars or black holes. Their brightness and temperature make them important for studying the structure and evolution of galaxies.
