Inferring a Dense Confined Circumstellar Medium around Supernova Progenitors via Long-term Hydrodynamical Evolution

Circumstellar interaction of supernova (SN) ejecta is an essential process in its evolution, and observations of SNe have found the signature of circumstellar interaction in both the early and late evolutionary phases of SNe. In this Letter, we show that if the SN forward shock plunges into a tenuou...
