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 (Ni) on the early-time color evolution of Type Ib and Ic supernovae (SNe Ib/Ic) using multi-group radiation hydrody…
Impact of binary interaction on the evolution of blue supergiants
Eoin Farrell, Jose Groh, Georges Meynet +5
A large fraction of massive stars evolve in interacting binary systems, which dramatically modifies the outcome of stellar evolution. We investigated the properties of blue supergi…
A Deep Near-Infrared [Fe II]+[Si I] Emission Line Image of the Supernova Remnant Cassiopeia A
Bon-Chul Koo, Hyun-Jeong Kim, Yong-Hyun Lee +4
We present a long-exposure (~10 hr) image of the supernova (SN) remnant Cassiopeia A (Cas A) obtained with the UKIRT 3.8-m telescope using a narrow band filter centered at 1.644 um…
Type IIP supernova light curves affected by the acceleration of red supergiant winds
Takashi J. Moriya, Francisco Förster, Sung-Chul Yoon +2
We introduce the first synthetic light-curve model set of Type IIP supernovae exploded within circumstellar media in which the acceleration of the red supergiant winds is taken int…
Supernovae from massive stars with extended tenuous envelopes
Luc Dessart, Sung-Chul Yoon, Eli Livne +1
Massive stars with a core-halo structure are interesting objects for stellar physics and hydrodynamics. Using simulations for stellar evolution, radiation hydrodynamics, and radiat…
