A likely supermassive neutron star might shed light on the mass gap between neutron stars and black holes
A team of astronomers recently identified a red giant star with an unseen binary companion after examining data from the Large Sky Area MultiObject Fiber Spectroscopic Telescope (LAMOST) and the Apache Point Observatory Galactic Evolution Experiment (APOGEE). Although the companion object can't be observed visually, astronomers can see the gravitational effects it has on the red giant star.
