* Sun Stars: "Sun star" usually refers to a star similar to our Sun, which is a yellow dwarf star. These stars are classified as main sequence stars, meaning they are fusing hydrogen into helium in their cores.
* Black Dwarfs: Black dwarfs are theoretical objects that form when a white dwarf star has cooled down to the point where it no longer emits any significant heat or light. They are formed over incredibly long timescales (trillions of years).
Key Differences:
* Formation: Sun stars are born from collapsing clouds of gas and dust, while black dwarfs are the final stage of a white dwarf star's evolution.
* Temperature and Light: Sun stars are hot and luminous, while black dwarfs are extremely cold and emit no visible light.
* Size: Sun stars are much larger than black dwarfs, which are about the size of the Earth.
In Summary: Black dwarfs are not a type of sun star. They are the extremely cold, theoretical remnants of white dwarf stars, formed after incredibly long periods of time.
