Description
Stripped-envelope core-collapse supernovae are the violent explosions that mark the death of a massive star that had some or all of its outer H and He layers stripped off. One class of stripped-envelope supernovae is the rare Type Ic-BL; these are the only events associated with the detection of a long-duration gamma-ray bursts, but it is still unclear why only some Ic-BLs accompany a gamma-ray burst detection. Radio observations probe the gas in the vicinity of a supernova, which contextualizes the lives of highly stripped stars and can tell us about which stars may produce a gamma-ray burst. In this talk, I will present radio observations of SN2022xxf, the nearest Ic-BL to date and discuss how its double-peaked light curve reveals the complex stripping mechanisms that shape these rare events.
