Description: 達到八倍太陽質量的恆星預計會以白矮星的形式結束其生命。這其中就包括我們的太陽。白矮星的密度非常高，一顆典型白矮星的質量與太陽相當，但被擠壓成了一個僅比地球略大的球。白矮星不再通過其內核的核反應產生能量，但會因為剩餘的能量而發光。溫度較高的白矮星會呈現出藍色或白色，這是因為它們的表面溫度非常高，會輻射出能量。白矮星的內核可能由氦、碳-氧或氧-氖-鎂組成，具體取決於恆星的初始質量。白矮星並不會在其自引力作用下收縮，這是由於其內部存在電子簡並壓——一種量子現象——帶來的阻力。電子簡並壓最大只能支持 1.4 倍太陽質量的白矮星。質量大於這個極限（稱為錢德拉塞卡極限）的恆星殘骸要麼是中子星，要麼是黑洞。
