Pre-explosion, explosion, and post-explosion jets in supernova SN 2019zrk

ABSTRACT I analyse some properties of the luminous transient event SN 2019zrk and conclude that jets were main powering sources pre-explosion outburst (pre-cursor) ejection a massive circumstellar matter (CSM), very energetic explosion itself, post-explosion bump in light curve. The energy source is mainly companion (main sequence, Wolf–Rayet, neutron star, or black hole) star accreted mass launched jets. find fast expansion CSM after acceleration by ejecta requires to be $\gtrsim 10^{52}\, {~\rm erg}$. Only jet-driven explosions can supply this such 2009ip-like transients. ejecta-CSM interaction extremely unlikely power bright at about 110 d explosion. Instead, show applying toy-model are most likely explanation for bump. leave open question whether itself outburst) was core collapse supernova (CCSN) common envelope (CEJSN). In study, further connect peculiar events, here CCSNe arguing drive all from regular through superluminous many other superenergetic including CEJSNe. Jet-powering cannot ignored when analysing these types
