Double-humped Super-luminous Supernovae

TL;DR

This paper discusses the dual-shock quark nova (dsQN) model as a mechanism for super-luminous supernovae, specifically explaining the double-humped light curve of SLSN 2006oz, and compares it with other proposed models.

Contribution

It introduces and supports the dsQN model as a plausible explanation for double-humped super-luminous supernovae, aligning with observed light curves.

Findings

The dsQN model predicts a normal supernova before the main SLSN event.

The model is consistent with the light curve of SLSN 2006oz.

Other mechanisms like pair instability and ejecta interaction are less consistent with the double-humped feature.

Abstract

Super-luminous supernova (SLSN) are supernovae showing extreme properties in their light-curves: high peak luminosities (more than 10 times brighter than bright SN Ia), and long durations. Several mechanisms have been proposed for SLSN, such as pair instability SN of a massive progenitor, interaction of the ejecta with a massive circumstellar shell, and the dual-shock quark nova (dsQN) model. The dual-shock quark nova model is unique in that it predicts a normal SN event will be seen about 10 days prior to the main SLSN event. The dsQN model is described here and shown that it is consistent with the light curve of the one currently known double-humped SLSN, 2006oz.
