One type of these bodies ceases to emit radiation at the so-called “death line.” A 2017 multi-messenger astronomy breakthrough involved measuring both gravitational waves and a gamma-ray burst from the merger of two of (-5[1])these bodies, (10[1]-5[2])known as a kilonova. (-5[2])An (-5[1])upper limit on these bodies’ mass is named for Tolman, Oppenheimer, and Volkov. A “glitch” (0[1])is a small increase in the frequency emitted by rapidly rotating examples (-5[1])of these bodies called pulsars. Stars whose mass is just above the Chandrasekar limit form one of these bodies after a supernova instead of a white dwarf.
