Title: A Study of Massive Star Evolution and Mass Loss With Multi-Wavelength Observations of Type IIn Supernovae
PI Name: Ori Fox
Type IIn supernovae (SNe IIn) are a rare (<10%) subclass of SNe that exhibit narrow emission lines due to a dense, pre-existing circumstellar medium (CSM). Although all evidence points to massive star progenitors, the precise stellar type remains elusive. Multi-wavelength observations can probe various aspects of shock interaction and dust formation for months to years after the radioactive emission fades. Here we submit a joint Spitzer/Chandra proposal to trace the mass-loss history of SNe IIn with a thorough, coordinated, multi-wavelength approach.
