Rare White Dwarf Pulsar Discovery Reveals Cosmic Deception.

A research team from the University of Warwick has discovered a rare white dwarf pulsar for only the second time, providing significant insights into stellar evolution. White dwarf pulsars include a rapidly spinning, burnt-out stellar remnant called a white dwarf, which lashes its neighbor – a red dwarf – with powerful beams of electrical particles and radiation, causing the entire system to brighten and fade dramatically over regular intervals. The discovery of J1912−4410 provided a critical step forward in understanding the origin of magnetic fields in white dwarfs, which can be more than a million times stronger than the magnetic field of the Sun, and the dynamo model helps to explain why.
