Ultralong Collapsars: These stellar-engine models can explain long durations but struggle to account for the specific timing of this event. Specifically, they cannot easily produce a 12-hour gradual rise in X-rays followed by a multi-hour peak, as the jet would have to fight through a massive progenitor star while its power is still very low. 2. White Dwarf (WD) Tidal Disruptions: While an Intermediate Mass Black Hole (IMBH) disrupting a White Dwarf could theoretically provide the necessary gravity, the numbers do not add up for this specific burst. The timing between flares is too long for a WD scenario, and the total energy required would demand an unrealistically narrow jet. When physical constraints like detonation are factored in, this model is considered highly unlikely. 3. Micro-TDEs (Main Sequence star by a stellar-mass BH/NS): This is considered a competitive alternative that can explain the burst's sub-second variability and long duration. However, it faces two main issues: current afterglow data suggests the surrounding gas density matches an IMBH environment better than a micro-TDE environment, and the burst’s extreme energy would require very high jet efficiency or a very narrow beam.
