SN 2009ip and SN 2010mc as dual-shock Quark-Novae

In recent years a number of double-humped supernovae(SNe)have been discovered.This is a feature predicted by the dual-shock Quark-Nova(QN)model where an SN explosion is followed(a few days to a few weeks later)by a QN explosion.SN 2009ip and SN 2010mc are the best observed examples of double-humped SNe.Here,we show that the dual-shock QN model naturally explains their light curves including the late time emission,which we attribute to the interaction between the mixed SN and QN ejecta and the surrounding circumstellar matter.Our model applies to any star(O-stars,luminous blue variables,Wolf-Rayet stars,etc.)provided that the mass involved in the SN explosion is～20 M which provides good conditions for forming a QN.
