White dwarfs are the remnants of low to medium mass stars that have exhausted their nuclear fuel and have collapsed under their own gravity. They are extremely dense objects, with masses comparable to that of the sun but packed into a volume roughly the size of Earth. White dwarfs are some of the oldest and most common stellar objects in the universe. Research on white dwarfs focuses on understanding their formation, evolution, and properties, as well as using them as a tool to study the history and dynamics of star systems. Some key areas of research include the study of the cooling rates of white dwarfs, the detection of circumstellar disks and planetary systems around white dwarfs, and the potential use of white dwarfs as standard candles for measuring cosmic distances. Overall, white dwarfs are a fascinating and important area of study in stellar astrophysics.
