List of hottest stars

Category:Lists of stars
This is an incomplete list of the hottest stars in the universe. Most of the hottest stars in the universe are Wolf–Rayet stars. They have temperatures of 50,000 to 200,000 degrees Celsius. White dwarfs and neutron stars can be much hotter than Wolf-Rayet stars. The hottest white dwarfs are about 200,000 degrees Celsius, while neutron stars can be hotter than 3 million degrees Celsius. Some of the information in the list below may not be 100% correct.
