Progenitor Constraint Incorporating Shell Merger: The Case of Supernova Remnant G359.0-0.9

Kai Matsunaga, Hiroyuki Uchida, Rei Enokiya +5

It is generally hard to put robust constraints on progenitor masses of supernovae (SNe) and remnants (SNRs) observationally, while they offer tantalizing clues to understanding exp…

Destratification in the Progenitor Interior of the Mg-rich Supernova Remnant N49B

Toshiki Sato, Kai Matsunaga, Ryo Sawada +6

Simulations of pre-supernova evolution suggest that some intense shell burning can be so active that, in extreme cases, it can merge with the outer shell, changing the initial cond…

Three-Dimensional Velocity Diagnostics to Constrain the Type Ia Origin of Tycho's Supernova Remnant

Hiroyuki Uchida, Tomoaki Kasuga, Keiichi Maeda +3

While various methods have been proposed to disentangle the progenitor system for Type Ia supernovae, their origin is still unclear. Circumstellar environment is a key to distingui…
