Project Details


Envelope-stripped, core-collapse SNe (i.e. Type Ibc) have recently enjoyed a surge of interest thanks to their association with Gamma-Ray Bursts (GRBs). The peculiar circumstances that enable a small fraction of SNe Ibc to launch a relativistic jet are not understood. Along the same line, the progenitors of SNe Ibc and their relation to those of GRBs have yet to be observationally identified. Here we propose a continuation of our coordinated Chandra-VLA program to enable progress. The primary goals are: (i) Constrain the pre-SN mass-loss history of the progenitor star by sampling the environment around H-stripped core-collapse SNe. (ii) Constrain the presence of engines driving the explosion of the most energetic SNe Ibc that are NOT observationally associated with GRB
