On the central engine of the fastest-declining Type I supernova SN2019bkc
Abstract
An analytic model is presented for the fastest-declining Type I supernova SN2019bkc. The model of the central engine consists of the magnetic dipole radiation from a non-explosive remnant of a double white dwarf merger. We consider the viscous evolution of the rotating remnant, which may lead to the diminishing energy supply in an appropriate time scale for the light curve.
