Title: Spectroscopic followup of shock breakout events
Abstract:
Observations of the shock breakout emission from Core Collapse Supernovae (CC
SNe) can provide a key measure of the progenitor star radius and the
structure and composition of its outer layers, very difficult to decipher
otherwise. Thus, observations of shock breakouts will dramatically extend our
ability to constrain the final stages of massive stars evolution. By cross
correlating CC SN discoveries from the Palomar Transient Factory (PTF) with
GALEX UV observations we have already detected several PTF CC SNe in the UV
shortly after explosion. Here, we request Gemini-N rapid, early-time ToO
spectroscopy of two PTF/GALEX SNe, discovered when no other telescope could
react. These data will measure crucial physical parameters of the explosion
(e.g., temperature, expansion velocity, dust extinction) that cannot be
determined at later time, and will allow rapid progress in our understanding
of the final stages of massive star evolution via this synergistic
Gemini/PTF/GALEX program.
