Constraining the Fraction of Core-Collapse Supernovae Harboring Choked Jets with High-energy Neutrinos

Understand

The joint observation of core-collapse supernovae with gamma-ray bursts shows that jets can be launched in the aftermath of stellar core collapse, likely by a newly formed black hole that accretes matter from the star.

• Such gamma-ray bursts have only been observed accompanying Type Ibc supernovae, indicating a stellar progenitor that lost its Hydrogen envelope before collapse.
• According to recent hypothesis it is possible that jets are launched in core-collapse events even when the progenitors still retain their Hydrogen envelopes, however, such jets are not able to burrow through the star and will be stalled into the interior of the progenitor star before escaping.
• These jets are called chocked jets.
