White dwarf - Wikipedia
White dwarfs are thought to be the final evolutionary state of stars whose mass is not high enough to become a neutron star or black hole.

White dwarf star | Definition, Size, Mass, Life Cycles, & Facts ...
White dwarf star, any of a class of faint stars representing the endpoint of the evolution of intermediate- and low-mass stars. White dwarf stars are characterized by a low luminosity, a mass on the order of that of the Sun, and a radius comparable to that of Earth.

White dwarfs: Facts about the dense stellar remnants
White dwarfs are hot, dense remnants of stars. They are the last observable stage of evolution for low and medium-mass stars including our sun.

What are white dwarf stars? How do they form? - EarthSky
White dwarfs are the hot, dense remnants of long-dead stars. They are stellar cores, left behind when stars exhaust their fuel supplies and blow their gases into space.

White Dwarf Stars - Imagine the Universe!
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula.

White Dwarf's Hidden Furnace Finally Comes Into View
A smaller white dwarf star (left) pulls material from a larger star into a swirling accretion disk. The pair is called an “intermediate polar,” and MIT astronomers used powerful telescopes to measure the system’s X-ray polarization for the first time, revealing key features at the center of its hottest, most extreme regions.

White Dwarfs Facts, Information and Photos - National Geographic
White dwarfs are stars that have burned up all of the hydrogen they once used as nuclear fuel. Fusion in a star's core produces heat and outward pressure, but this pressure is kept in balance...

The Lifecycle and Impact of White Dwarfs - Simple Science
Learn about white dwarfs, their formation, and their roles in stellar evolution. White dwarfs are a common outcome in the life cycle of stars. They are the...

White Dwarf: Definition, Size, Temperature And Other Facts
One of the forms it could take is of a White Dwarf, where the star becomes very dense, as a massive star (like the Sun) gets compressed into a smaller volume (perhaps the size of Earth). White dwarfs have low luminosity, which comes from the stored thermal energy that gets emitted.

White Dwarf Research Corporation - Education - Ask an Astronomer ...
A white dwarf is a type of star that contains about as much matter as the Sun, but packed into a size comparable to the Earth. The majority of white dwarfs are thought to be made mostly of carbon and oxygen.
