Jittering jets in stripped-envelope core-collapse supernovae
We compare the expected explosion time of core-collapse supernovae (CCSNe) in the jittering jets explosion mechanism (JJEM) to that in the neutrino-driven (the delayed neutrino) mechanism, and conclude that for most, but not all, stellar models, even when the neutrino-driven mechanism might have led to an explosion, the JJEM starts to operate before the neutrino mechanism fully revives the stalled shock. To achieve this goal, we conduct comprehensive one-dimensional stellar evolution simulations using the code \textsc{mesa} to determine the expected explosion time according to the JJEM, which corresponds to the time when the inner convective layer of the core is accreted onto the newly born neutron star (NS). We present results for many hydrogen-rich, hydrogen-stripped, and helium+hydrogen-stripped envelope CCSN progenitor models. We find that most, but not all, of our models in the initial mass range of $M_{\rm ZAMS}=12M_\odot$ to $M_{\rm ZAMS}=40M_\odot$, have at least one strong convective zone inside the mass coordinate that is the maximum baryonic mass of an NS, $m \simeq 2.65\ M_\odot$, which can facilitate the JJEM. This study contributes to establishing the JJEM as a viable explosion mechanism of CCSNe.
