Created following Type II, Ib, or Ic supernovae and lighter than black holes, for ten points, what remnants of stellar collapse are nonetheless so massive that they contain matter too dense for electrons to remain in orbit around protons?
Geminga is a rare example of a radio-quiet one, and their solid ionic crusts can break up in so-called starquakes. Above the Tolman-Oppenheimer- Volkoff limit of 2-3 solar masses, they may be less likely than quark stars, but they are the only compact objects just above the Chandrasekhar limit on the size of a white dwarf. The periodic radiation emitted along the axes of their extremely fast rotation gives most of them the name of pulsars.
