Neutron-Star – Black-Hole Coalescence

Neutron-Star – Black-Hole Coalescence

with tidal disruption

The images show a simulation of a neutron-star–black-hole coalescence in which the neutron star is tidally disrupted during the merger.
In general, tidal disruption is present for low-mass black holes, prograde black hole spins, or large neutron star radii. However, such scenarios seem less present in nature, e.g., the neutron-star–black-hole coalescences GW200105 and GW200115 showed both no sign of tidal disruption.
