red dwarf

Artist's impression of a white dwarf pulsar. In this binary star system, a rapidly spinning white dwarf (right) accelerates electrons to nearly the speed of light. These high-energy particles produce bursts of radiation that strike the accompanying red dwarf star (left), causing the entire system to pulsate from the radio to the X-ray range. Credit: M.

We just found a rare white dwarf pulsar. The discovery of J1912-4410 - just 773 light-years away from Earth provides new insight into how stars evolve.
