Diagram of stellar evolution, showing the various stages of stars with different masses. A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently to no longer emit significant heat or light.
The ultimate stage of stellar evolution for many stars is a black dwarf. Because they emit no heat or light, these objects would be a challenge to detect if they existed today.
Black Dwarf. An artist's concept of a dark brown dwarf, which make resemble the black dwarfs predicted to form in the future. NASA / JPL-Caltech. Even white dwarfs won’t last forever,...
When the sun eventually dies it would become an object that doesn't emit light and heat, devoid of any radiation, a black dwarf. Black dwarfs are a projected state of a low mass star, they don't currently exist as our universe is not old enough for them to form.
Black dwarfs are essentially dead stars that no longer emit light or heat. They are incredibly dense objects, with a mass similar to that of the Sun but compressed into a much smaller volume. Due to their lack of nuclear fusion, black dwarfs do not generate energy and are therefore cold and dark.
The ultimate stage of stellar evolution for many stars is a black dwarf. Because they emit no heat or light, these objects would be a challenge to detect if they existed today. However, black dwarfs take quadrillions of years to form.
New theoretical work by Caplan, an assistant professor of physics at Illinois State University, finds that many white dwarfs may explode in supernova in the distant far future, long after...
A different type of stellar explosion, called a black dwarf supernova, may light up the darkness at the end of the universe.
A black dwarf is a white dwarf that has cooled down to the temperature of the cosmic microwave background, and so is invisible. Unlike red dwarfs, brown dwarfs, and white dwarfs, black dwarfs...
Ever heard of a black dwarf star? These hypothetical stars are so old they would need to be older than the current age of the Universe.
