The aim is to explain the unusual timescales and flaring structure of gamma-ray burst GRB 250702B using a white dwarf and black hole model.
Analyzed the dynamics of a white dwarf on a highly eccentric orbit around an intermediate-mass black hole.
Considered tidal disruptions leading to mass accretion at pericenter and associated gamma-ray bursts.
Evaluated orbital precession effects on flare observations and potential afterglow enhancements.
Demonstrated that individual flares occur due to material stripping near pericenter with typical mass ΔM ≈ 2 × 10−2 M⊙.
Predicted approximately 40 jet-launch episodes, with four visible from a direct line of sight due to orbital precession.
Suggests off-axis jets enhance radio afterglow by an order of magnitude, offering new testing predictions.
