Dwarfs

Dwarfs are a type of star that are smaller and cooler than our Sun. They have less mass and luminosity, meaning they shine less brightly. Despite their size, they are very common in the universe. Dwarfs come in several categories, such as red dwarfs, which are cool and reddish in color, and white dwarfs, which are the remnants of stars that have exhausted their fuel. They play a crucial role in understanding stellar evolution and are important in the study of exoplanets, as many planets are found orbiting dwarf stars.
