提出了衰减最快的 I 型超新星 SN2019bkc 的解析模型。中央引擎的模型由来自双白矮星合并的非爆炸残余物的磁偶极子辐射组成。我们考虑旋转残余物的粘性演化,这可能导致光变曲线在适当的时间尺度内能量供应减少。
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.
