Fallback accretion powered supernova light curves based on a neutrino-driven explosion simulation of a 40 Msun star

Understand

We present synthetic light curves of fallback-powered supernovae based on a neutrino-driven explosion of a 40 Msun zero-metallicity star with significant fallback accretion onto a black hole that was previously simulated by Chan et al.

• (2018) until shock breakout.
• Here, we investigate the light curve properties of the explosion after shock breakout for various fallback models.
• Without extra power from fallback accretion, the light curve is that of a Type IIP supernova with a plateau magnitude of around -14 mag and a plateau duration of 40 days.
