Glossary term: 白矮星
Description: 达到八倍太阳质量的恒星预计会以白矮星的形式结束其生命。这其中就包括我们的太阳。白矮星的密度非常高，一颗典型白矮星的质量与太阳相当，但被挤压成了一个仅比地球略大的球。白矮星不再通过其内核的核反应产生能量，但会因为剩余的能量而发光。温度较高的白矮星会呈现出蓝色或白色，这是因为它们的表面温度非常高，会辐射出能量。白矮星的内核可能由氦、碳-氧或氧-氖-镁组成，具体取决于恒星的初始质量。白矮星并不会在其自引力作用下收缩，这是由于其内部存在电子简并压——一种量子现象——带来的阻力。电子简并压最大只能支持 1.4 倍太阳质量的白矮星。质量大于这个极限（称为钱德拉塞卡极限）的恒星残骸要么是中子星，要么是黑洞。
