The recently reported Type II Gamma-ray Burst (GRB) 200826A challenges the collapsar models by questioning how they can generate a genuinely short duration of the event. This paper proposes that the burst can originate from the collapse of a Thorne-Zytkow-like Object (TZlO). The TZlO consists of a central neutron star (NS) with a dense white dwarf (WD) material envelope and a disk, which are formed as the aftermath of a WD-NS coalescence. We found the collapse of such a TZlO can naturally…
