Observational signatures of stellar explosions driven by relativistic jets

Understand

The role of relativistic jets in unbinding the stellar envelope during a supernova (SN) associated with a gamma-ray burst (GRB) is unclear.

• To study that, we explore observational signatures of stellar explosions that are driven by jets.
• We focus on the final velocity distribution of the outflow in such explosions and compare its observational imprints to SN/GRB data.
• We find that jet driven explosions produce an outflow with a flat distribution of energy per logarithmic scale of proper velocity.
