Accretion disc, pulling matter away from the companion star, an inward velocity from the gravitational pull makes the fast speed convert to heat, and hot things produce x-rays for us to observe. The fusion results in an iron core, sometimes it produces gamma-ray bursts. Very luminous, as much energy as a supernovae. Forming jets of particles moving at the speed of light, shredding the star apart.
