The accretion process in neutron star binaries differs from that of white dwarf binaries due to the absence of a solid surface in black holes. Neutron stars experience higher energy interactions during accretion, leading to significant thermonuclear explosions when matter accumulates. This process is more energetic compared to white dwarf accretion. The unique characteristics of neutron stars result in distinct outcomes during the accretion phase. Understanding these differences is crucial for astrophysical studies of binary systems.

The acretion process between a white dwar binary and blakc hole binary is significantly different as the black hole has no solid surface. So am I right to presume that a neutron star binary should be the same process but with higher energies than than white dwarf case?

I'm no expert but I would say yes. In neutron stars usually the matter accumulates until a gargantuan thermonuclear explosion occurs.

Such objects are very bright (obiously) and very energetic. The article indicates that AT 2024wpp had a peak luminosity of 2-4 x...
