B-type stars

B-type stars are hot, luminous stars with a blue-white appearance, characterized by temperatures between 10,000 and 30,000 degrees Celsius. They are more massive than our Sun, often about 2 to 16 times its mass. These stars burn their fuel quickly, leading to shorter lifespans—typically a few million years. B-type stars are important in astronomy because they often form in clusters and can influence their surroundings through intense radiation and stellar winds. They also serve as key markers in understanding the life cycles of massive stars and the evolution of galaxies.
