The Radio Properties of Type Ibc Supernovae
Over the past few years, long-duration γ-ray bursts (GRBs), including the subclass of Xray flashes (XRFs), have been revealed to be a rare variety of Type Ibc supernova (SN Ibc). While all these events result from the death of massive stars, the electromagnetic luminosities of GRBs and XRFs exceed those of ordinary Type Ibc SNe by many orders of magnitude. The observed diversity of stellar deat...
متن کاملEvolution of progenitor stars of Type Ibc supernovae and long gamma-ray bursts
We discuss how rotation and binary interactions may be related to the diversity of type Ibc supernovae and long gamma-ray bursts. After presenting recent evolutionary models of massive single and binary stars including rotation, the Tayler-Spruit dynamo and binary interactions, we argue that the nature of SNe Ibc progenitors from binary systems may not significantly differ from that of single s...
متن کاملOn the progenitor of the Type Ibc supernova 2012fh
Little is observationally known about the progenitors of Type Ibc supernovae (SNe) or the typical activity of SNe progenitors in their final years. Here, we analyze deep Large Binocular Telescope imaging data spanning the 4 years before and after the Type Ibc SN 2012fh using difference imaging. We place 1σ upper limits on the detection of the progenitor star at MU > −3.8, MB > −3.1, MV > −3.8, ...
متن کاملThe death of massive stars – II. Observational constraints on the progenitors of Type Ibc supernovae
The progenitors of many Type II core-collapse supernovae (SNe) have now been identified directly on pre-discovery imaging. Here, we present an extensive search for the progenitors of Type Ibc SNe in all available pre-discovery imaging since 1998. There are 12 Type Ibc SNe with no detections of progenitors in either deep ground-based or Hubble Space Telescope archival imaging. The deepest absolu...
متن کاملConstraints on the progenitor systems of type Ia supernovae
UVOIR bolometric light curves provide a valuable insight into the nature of type Ia supernovae. We present an analysis of sixteen well-observed SNe Ia. Constraints are placed on several global parameters concerning the progenitor system, explosion mechanism and subsequent radiation transport. By fitting a radioactive decay energy deposition function to the quasiexponential phase (50 to 100 days...
