blue-white stars

Blue-white stars are very hot, luminous stars with surface temperatures typically between 10,000 to 30,000°C (18,000 to 54,000°F). Their high temperature causes them to emit a blue or white light, making them appear brighter and more energetic than cooler, yellow or red stars like the Sun. These stars belong to the spectral types O, B, or A. They often have shorter lifespans due to their rapid consumption of nuclear fuel. Blue-white stars are common in young, active star-forming regions of galaxies and are important in understanding stellar evolution and the makeup of our universe.
