H. Marion Harvard University N ------------------------------------------------------------------------------------ Abstract The UV spectrum of a core collapse SN encodes unique information about nucleosynthesis, the star's mass loss history, shock physics, and dust formation. This proposal aims at a detailed study of one bright core collapse SN, discoved as a result of the many ongoing surveys, either a Type IIP, IIn or Ib or Ic supernova. We will address the role of circumstellar interaction and mass loss through CNO lines in the UV, the nature of dust formation from UV line profiles, and we will use the UV continuum as a diagnostic of non-thermal emission from the shock. The overall goal is to achieve a better understanding of these objects by combining ground-based observations with complementary HST data. In cycle 17 and cycle 18 we obtained excellent data for SN 2010al and SN 2010jl that live up to our expectations. In the past, we have used HST to obtain critical UV spectra from the explosion to the nebular phase with good results for a limited number of objects. The advent of COS provides new capability for UV observations which we would like to exploit. When nature provides a bright candidate, HST should be ready to respond. ------------------------------------------------------------------------------------ Observations Description ------------------------ first visit will be just STIS/CCD second visit STISCCD+COS, 20-40 days after first visit thrid visit STIS/CCD+COS, 60=80 days after first visit 12540( 11) -
