Type I Superluminous Supernovae as Explosions inside Non-Hydrogen Circumstellar Envelopes

Understand

A number of Type I (hydrogenless) superluminous supernova (SLSN) events have been discovered recently.

• However, their nature remains debatable.
• One of the most promising ideas is the shock-interaction mechanism, but only simplified semi-analytical models have been applied so far.
• We simulate light curves for several Type I SLSN (SLSN-I) models enshrouded by dense, non-hydrogen circumstellar envelopes, using a multi-group radiation hydrodynamics code that predicts not only bolometric, but also multicolor light curves.
