“…Recent studies concentrate on two core collapse supernova (CCSN) explosion mechanisms that utilize the gravitational energy that the core of a massive star releases as it collapses to form a neutron star (NS). These are the delayed neutrino mechanism (Bethe & Wilson 1985; for later studies see, e.g., Heger et al 2003;Janka 2012;Nordhaus et al 2012;Couch & Ott 2013;Bruenn et al 2016;Janka et al 2016;O'Connor & Couch 2018;Müller et al 2019;Burrows & Vartanyan 2021;Fujibayashi et al 2021;Boccioli et al 2022;Nakamura et al 2022) and the jittering jets explosion mechanism (Soker 2010; for later papers see, e.g., Papish & Soker 2014;Gilkis & Soker 2015;Soker 2019;Quataert et al 2019;Soker 2020;Antoni & Quataert 2022;Shishkin & Soker 2022;Soker 2022aSoker , 2022b.…”

I examine recent fittings of luminous supernovae (LSNe) with extra energy sources of magnetar and helium burning and find that in about half of these LSNe the fitting parameters have some problems. In some LSNe the total energy of these two energy sources is larger than the kinetic energy of the ejecta that the fitting yields. In some other LSNe the total energy of the delayed neutrino explosion mechanism and these two extra sources combined is smaller than the kinetic energy that the fitting yields. These difficulties suggest that, like earlier claims that jets power superluminous supernovae (SLSNe), jets also power the less luminous LSNe. A magnetar might also supply energy. However, in most cases jets supply more energy than the magnetar, during the explosion and possibly at late times. I strengthen an earlier claim that jets launched at magnetar birth cannot be ignored. I explain the trend of maximum rise time for a given luminosity of hydrogen deficient core collapse supernovae, in particular LSNe and SLSNe, with a toy model of jets that are active for a long time after explosion.

Neutron Star Kicks and Implications for Their Rotation at Birth

Neutron stars are born out of core-collapse supernovae, and they are imparted natal kicks at birth as a consequence of asymmetric ejection of matter and possibly neutrinos. Unless the force resulting from the kicks is exerted exactly at their center, it will also cause the neutron star to rotate. In this paper, we discuss the possibility that neutron stars may receive off-center natal kicks at birth, which imprint a natal rotation. In this scenario, the observed pulsar spin and transverse velocity in the Galaxy are expected to correlate. We develop a model of the natal rotation imparted to neutron stars and constrain it by the observed population of pulsars in our Galaxy. When considering a single-kick position parameter, we find that the location of the off-center kick is R kick = 2.03 − 1.69 + 3.74 km at 90% confidence, and is robust when considering pulsars with different observed periods, transverse velocities, and ages. Nonetheless, the model encounters challenges in effectively fitting the data, particularly at small transverse velocities, prompting the exploration of alternative models that include more complex physics. Our framework could be used as a guide for core-collapse simulations of massive stars.
