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 | 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 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 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...
Dead Stars Aren’t So Dead: Scientists Discover White Dwarfs Can Heat Up ...
White dwarfs are among the most haunting objects in the universe: the compact remains of stars that once blazed with light and life. They are extraordinarily dense—a teaspoon of white dwarf matter would weigh several tons—and yet small enough to fit within the size of Earth.
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 Dwarfs: The Cooling Stars of the Universe - Simple Science
Explore the role of reaction rates in white dwarf evolution and pulsation patterns. White dwarfs are the remnants of stars that have burned out their fuel....
White Dwarf Devours an Icy Pluto-Like World
Hubble has spotted a white dwarf star consuming a Pluto-like icy body 260 light-years away. Discover what this rare event reveals about water in space.
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.
