Neutron stars are the incredibly
dense remnants left behind after supernova explosions.
Neutron stars are
dense remnants of stars gone supernova, packing the mass of the sun into a sphere the size of a city.
Two common models for gamma - ray emission from FRBs exist: one invoking magnetic flare events from magnetars — highly magnetized neutron stars that are
the dense remnants of collapsed stars — and another invoking the catastrophic merger of two neutron stars, colliding to form a black hole.
Current theory also suggests that if the doomed star holds less than 20 times the sun's mass, its explosive death should produce a small but extremely
dense remnant called a neutron star.
This animation shows the explosion of a white dwarf, an extremely
dense remnant of a star that can no longer burn nuclear fuel at its core.

According to the researchers, there are two possible scenarios in which such a cloud could have been created — the first one that involves the expanding gas shell of the supernova
remnant passing by a static black hole, and the other wherein a fast - moving black hole plunges through a cloud of
dense gas that is then dragged along by the former's strong gravity.
