Bookmark or Share- NASA – How White Dwarf Stars Get Their ‘Kicks’ - Science@NASAThe team studied 22 young white dwarfs less than 800 million years old and 62 older white dwarfs between 1.4 and 3.5 billion years old. The astronomers distinguished the younger from the older white dwarfs based on their color and brightness. The younger white dwarfs are hotter and therefore bluer and brighter than the older ones.
- Imagine the Universe!An Artist's conception of the evolution of our Sun (left) through the red giant stage (center) and onto a white dwarf (right). A typical white dwarf is half as massive as the Sun, yet only slightly bigger than Earth. An Earth-sized white dwarf has a density of 1 x 10 9 kg/m 3 . Earth itself has an average density of only 5.4 x 10 3 kg/m 3.
- White Dwarf Stars: The Tiny Giants Revealing the Universe's SecretsWhite dwarfs are cosmic time capsules. They hold the history of their parent star and offer a glimpse into the future of our own Sun. By studying these celestial objects, scientists can learn ...
- Types - NASA ScienceFor Stargazers: White dwarfs are too dim to see with the unaided eye, although some can be found in binary systems with an easily seen main sequence star. Procyon B is an example in the northern constellation Canis Minor. If you have a telescope at home, though, you can see solitary white dwarfs LP 145-141 in the southern constellation Musca and Van Maanen’s star in the northern ...
- White dwarf star | Definition, Size, Mass, Life Cycles, & Factswhite dwarf star, any of a class of faint stars representing the endpoint of the evolution of intermediate- and low-mass stars. 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.
