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 stars, so called because of the white colour of the first few that were discovered, are characterized by a low luminosity, a mass on the order of that of the Sun, and a radius comparable to that of Earth.
NASA’s IXPE Measures White Dwarf Star for First Time
This artist’s concept depicts a smaller white dwarf star pulling material from a larger star, right, into an accretion disk. Earlier this year, scientists used NASA’s IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star and its X-ray polarization.
White dwarfs: Facts about the dense stellar remnants | Space
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.
White Dwarf - ESA/Hubble
A white dwarf is the stellar core left behind after a dying star has exhausted its nuclear fuel and expelled its outer layers to form a planetary nebula. The ultimate fate of a star depends on its initial mass.
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.
NASA captures mind-blowing 1st peek inside a white dwarf system - MSN
NASA has finally peered into the heart of a white dwarf system in a way astronomers have been chasing for decades, turning a once-theoretical picture of stellar cannibalism into a mapped ...
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...
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 Dwarfs – Definition & Detailed Explanation - Sentinel Mission
White dwarfs are formed at the end of a star’s life cycle. When a star runs out of nuclear fuel, it can no longer support itself against gravity, causing it to collapse.
