two times the mass of the sun but much smaller even than a white dwarf.
mass of the neutron star and its orbiting companion, a white dwarf star.
The finding is significant because, until now, astronomers had not found direct evidence of a  planet that had survived the transition of a  star into a white dwarf.
approximately a  solar mass of 56Ni is formed and ejected from a white dwarf which accretes mass from a  binary companion and is raised over the Chandrasekhar limit and explodes.
Even if a white dwarf had formed at the moment of the Big Bang- which is impossible, since a  star must pass through several evolutionary stages that take at least a  billion years total- it would still be a white dwarf today, having not yet sufficiently cooled.
compression to take place, known as a white dwarf.
like 90 percent of other stars, our Sun is most likely to shrink down from a  red giant to become a white dwarf and then end as a  planetary nebula.
Sirius B, is a  star that has already evolved off the main sequence and become a white dwarf.
Typically Barium stars are close binaries with a white dwarf companion, but no companion has been detected for ο Virginis.[2] It has been suggested that an  excess SiIV emission flux is
That would mean it collapsed from a white dwarf into a  neutron star as a  result of feeding off the red giant over a  long time, rather than becoming a  neutron star as a  result of a  more traditional supernova explosion
A white dwarf is a  star composed of electron-degenerate matter, thought to be the final stage in
As a white dwarf rabbit, she often finds herself being treated as a  fragile individual by society and wants to be validated as a  person;
one of the last phases of stellar evolution before the star dies and becomes a white dwarf.
Because the time required for a white dwarf to reach this state is calculated to be longer than the current age of the universe(13.8 billion years), no black dwarfs  are expected
Because the length of time it takes for a white dwarf to reach this state is calculated to be longer than the current age of the universe, it is thought that no black dwarfs  yet exist; the oldest white dwarfs  still radiate at temperatures of a  few thousand kelvins.
Occasionally, a white dwarf gains mass from another source- for example, a  binary star
own beautiful nebula and then fade away as a white dwarf star," Howard Bond,
follow more complex evolutionary paths, such as mass transfer onto a white dwarf companion that can potentially cause a  supernova.
Sirius B is a white dwarf.
