Type Ib/Ic supernovae: effect of nickel mixing on the early-time color evolution and implications for the progenitors

Sung-Chul Yoon, Wonseok Chun, Alexey Tolstov +2

We investigate the effect of mixing of radioactive nickel (${}^{56}$Ni) on the early-time color evolution of Type Ib and Ic supernovae (SNe Ib/Ic) using multi-group radiation hydrody…
