A-type stars

A-type stars are a classification of stars that are hotter and more massive than our Sun. They have surface temperatures ranging from about 7,500 to 10,000 degrees Celsius. A-type stars emit a strong blue-white light and typically appear bluish in the night sky. They are known for their striking brightness and can be found in various stages of stellar evolution, often burning hydrogen in their cores. Notable examples include Sirius A, the brightest star visible from Earth, and Vega, which is part of the Lyra constellation. A-type stars generally have short lifespans, living only a few hundred million years.
