Astronomers Identify the Lightest Known Double Neutron Star System, Sharpening the Physics of Stellar Death
Astronomers have identified the lowest-mass double neutron star system yet observed, a rare binary that offers a new laboratory for testing how massive stars end their lives and how compact objects evolve in pairs. The finding strengthens the scientific case for using neutron-star binaries to probe extreme gravity, dense matter, and the origins of gravitational-wave events.
