Characterisation of Supernovae Interacting with Dense Circumstellar Matter with a Flat Density Profile

Ryotaro Chiba, Takashi J. Moriya

Interaction between supernova (SN) ejecta and dense circumstellar medium (CSM) with a flat density structure ($\rho \propto r^{-s},s<1.5$) was recently proposed as a possible mechan…
