The class of supernova progenitors that result from fatal common envelope evolution

摘要: I construct the class of supernovae and supernova progenitors that result from fatal common envelope evolution (CEE). The CEE are stellar binary systems where a companion spirals-in inside giant star merges with core. can be neutron (NS; or black hole) destroys core by forms jets (CEJSN), white dwarf (WD) to form massive WD later might explode as Type Ia (the degenerate scenario), main sequence companion. In latter case outcome collapse (CCSN) blue giant, CCSN type IIb Ib. another member this two stars merge cores spiral-in toward each other explodes circumstellar matter (CSM). discuss members class, their characteristics, properties. find events account for $\\approx$$6%$-$10%$ all CCSNe, raise possibility large fraction peculiar rare CEE. study these will bring insights on types progenitors, well
