A white dwarf on an eccentric orbit around an intermediate-mass black hole undergoes successive partial tidal disruptions, with frame-dragging precession producing the irregular flares observed in GRB 250702B.

Tidal disruptions of 0.6 solar mass white dwarfs by 500 solar mass black holes can produce asymmetrical thermonuclear supernovae with 56Ni fractions from 1% to 82% depending on impact parameter and strong viewing-angle dependence in light curves and spectra.
SPH simulations of repeated partial disruptions in 16 WD-BH/NS systems predict three categories of periodically modulated X-ray/GRB transients whose durations and peak rates depend on mass ratio and compactness.
