Second White Dwarf Pulsar Discovered by Astronomers

Astronomers have discovered a white dwarf pulsar called J1912-4410, which is part of a binary pair that includes a red dwarf star. This is the second known white dwarf pulsar in the galaxy, and it challenges theoretical models describing white dwarfs. The white dwarf pulsar is cooler than the Sun, has a strong magnetic field, and spins on its axis 300 times faster than Earth does. The M-dwarf stellar companions also play a role in the pulsar activity. The discovery of J1912-4410 provides a critical step forward in understanding the origin of magnetic fields in white dwarfs.
