White Dwarf Meaning In Bengali শ্বেত বামন
White Dwarf
শ্বেতবামন,
Definition
1) In astronomy, a white dwarf is a small, extremely dense star that is near the end of its life cycle. It is the remnant of a sun-like star that has exhausted its nuclear fuel and has collapsed to a very small size, roughly the size of Earth.
2) White dwarfs are typically composed mostly of electron-degenerate matter, resulting in a high density that causes the star to radiate energy at a slow rate, eventually cooling and fading into a black dwarf.
3) White dwarfs are found in the later stages of stellar evolution, following processes such as the expulsion of a planetary nebula by the star's outer layers and the collapse of the remaining core into a degenerate state.
