Heaviest Neutron Star to date is a ‘Black Widow’ Eating its Mate

PSR J0952-0607: The Fastest and Heaviest Known Galactic Neutron Star
A spinning neutron star periodically swings its radio (green) and gamma-ray (magenta) beams past Earth in this artist’s concept of a black widow pulsar. The neutron star/pulsar heats the facing side of its stellar partner (right) to temperatures twice as hot as the sun’s surface and slowly evaporates it. Credit: NASA’s Goddard Space Flight Center

A dense, collapsed star spinning 707 times per second—making it one of the fastest spinning neutron stars in the Milky Way galaxy—has shredded and consumed nearly the entire mass of its stellar companion and, in the process, grown into the heaviest neutron star observed to date.

Weighing this record-setting neutron star, which tops the charts at 2...
