Grb060218: a Relativistic Supernova Shock Breakout
We show that the prompt and afterglow X-ray emission of GRB060218, as well as its early (t 1 d) optical-UV emission, can be explained by a model in which a radiation-mediated shock propagates through a compact progenitor star into a dense wind. The prompt thermal X-ray emission is produced in this model as the mildly relativistic shock, β ≈ 0.85 carrying few ×10 49 erg, reaches the wind (Thomso...
متن کاملSupernova shock breakout from a red supergiant.
Massive stars undergo a violent death when the supply of nuclear fuel in their cores is exhausted, resulting in a catastrophic "core-collapse" supernova. Such events are usually only detected at least a few days after the star has exploded. Observations of the supernova SNLS-04D2dc with the Galaxy Evolution Explorer space telescope reveal a radiative precursor from the supernova shock before th...
متن کاملShock Breakout from Type Ia Supernova
The mode of explosive burning in Type Ia SNe remains an outstanding problem. It is generally thought to begin as a subsonic deflagration, but this may transition into a supersonic detonation (the DDT). We argue that this transition leads to a breakout shock, which would provide the first unambiguous evidence that DDTs occur. Its main features are a hard X-ray flash (∼ 20 keV) lasting ∼ 10−2 s w...
متن کاملDid we observe the supernova shock breakout in GRB 060218 ?
If the early optical data of GRB 060218 up to 10 s are interpreted as the black-body flux associated with the supernova shock breakout, we can derive lower limits to the bolometric luminosity and energetics of this black–body component. These limits are more severe for the very early data that imply energetics of order of 10 erg. These values, puzzlingly large, are rather independent of the ass...
متن کاملNeutrino emission from a GRB afterglow shock during an inner supernova shock breakout
The observations of a nearby low-luminosity gamma-ray burst (GRB) 060218 associated with supernova SN 2006aj may imply an interesting astronomical picture where a supernova shock breakout locates behind a relativistic GRB jet. Based on this picture , we study neutrino emission for early afterglows of GRB 060218-like GRBs, where neutrinos are expected to be produced from photopion interactions i...
