An axisymmetric shock breakout indicated by prompt polarized emission from the type II supernova 2024ggi

Yi Yang, Xudong Wen, Lifan Wang +18

The death of massive stars is triggered by an infall-induced bounce shock that disrupts the star. How such a shock is launched and propagates through the star is a decade-long puzz…
