They found that other dense cosmic bodies, like neutron stars and white dwarfs ... the same team argued that the intense gravitational pull of any compact object—not just a black hole—could ...

There, a complex symphony of gravitational waves is being generated by a multitude of cosmic sources, including a supermassive black hole, binary black holes, neutron stars, and white dwarfs.

The detection, described on 22 May in Science 1, sheds light on processes that give rise to the spectacular mergers seen by gravitational-wave observatories — involving two neutron stars ...

You need to start with a star shedding material ahead of the explosion, something common in several types of supernova.

Based on their new estimates, both neutron stars and stellar black holes take ... After all, we have mass and therefore a miniscule amount of gravitational pull. Barring no other external factors ...
