If the mass of the core after a supernova explosion is more than 1. 4 but less than about 3 solar masses, then electron degenerate pressure is not strong enough to support the star. the star will contract to a size even smaller than the white dwarf. the electrons are squeezed into the nuclei and are combined with the protons to form neutrons
假若在超新星爆發后，剩餘核心質量介乎太陽質量的1 . 4至3倍，那麼核心中的電子簡並壓力便再不足以抵抗強大的引力，恆星會進一步收縮，直至電子亦被擠壓至原子核內，和質子結合成為中子。
