white dwarf star

基本解释

This leads the researchers to suspect that a white dwarf star strayed too close to the intermediate-mass black hole and was ripped apart by tidal forces.
这导致研究人员怀疑一个迷途的白矮星离某个中等质量黑洞太接近了，并受其潮汐引力的撕扯。
In a later stage of the sun's death throes, when it contracts into a compact white dwarf star, part of this rocky material could rain down into the white dwarf's hot atmosphere.
在垂死挣扎的后期，太阳会收缩成为高密度的白矮星，这时部分岩石物质可能会降落到白矮星炽热的大气中。

The primary target is a white dwarf star known as GD358 in the constellation Hercules.

These new models of failed supernovae demonstrate how both normal brightness and extremely dim supernovae are generated from the same basic picture of a nuclear-burning white dwarf star, he added.

Standard Type Ia supernovae are binary systems in which a white dwarf star draws so much matter from its companion (often a red giant) that it undergoes a kind of energy overload and detonates.
