B-type Main Sequence Stars are a class of stars that are hotter and more massive than the Sun. They typically have surface temperatures ranging from 10,000 to 30,000 Kelvin and are known for their blue-white color. These stars burn hydrogen in their cores at a much faster rate than cooler stars, leading to shorter lifespans of only a few million years. Due to their high temperatures, B-type stars emit a significant amount of ultraviolet radiation, which can influence the surrounding environment, including the formation of new stars. Examples of B-type stars include Sirius B and Altair, both of which are prominent in our night sky.
