Abstract: | Common envelope jets supernovae (CEJSNe) serve as astrophysical sites of high energy processes. We present two scenarios that might account for enigmatic processes studied over the past years. 1.We study r-process feasibility inside jets launched by a cold neutron star spiralling-in inside the core of a red supergiant (RSG), and find that such CEJSN events might be a significant source of heavy r-process elements in the early Universe. 2.We study high energy neutrino emission from relativistic jets launched by a black hole spiralling-in inside the envelope of a RSG, and find that CEJSNe with a BH companion are a potential source for the ≳10^15eV neutrinos detected by IceCube. |
