Massive Neutron Star Is the Definition of Extreme

NewImage‘New research published this week in the Astrophysical Journal describes one of the most massive neutron stars ever detected, an object containing 2.3 solar masses. Only one known neutron star tops it: a behemoth discovered seven years ago that weighed in at 2.4 solar masses. In total, out of the approximately 2,000 neutron stars known to astronomers, only four are more than two solar masses. Super-massive neutron stars are thus relatively rare, and they exist at the limits of what’s physically possible—making them exceptionally important objects of inquiry, both for astronomers and for particle physicists….’
