Abstract
Current cc-SN models predict overproduction of 44Ti compared to observations. We present a model for an alternative channel where a cc-SN explosion is followed by a neutron star detonation (Quark Nova or QN), resulting in a spallation reaction of SN ejecta that produces 44Ti. We can achieve a 44Ti production of ~ 10^-4 Msun with our model under the right time delay between the QN and the SN. Our model also produces unique signals not found in standard, cc-SN nucleosynthesis models. Some of these unique signals include a significantly large production of 7Be and 22Na. We discuss some of these signals by analyzing the late time light curve and gamma spectroscopy of our model.
