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