Confined Dense Circumstellar Material Surrounding a Regular Type II Supernova: The Unique Flash-Spectroscopy Event of SN 2013fs
O. Yaron, D. A. Perley, A. Gal-Yam +30
With the advent of new wide-field, high-cadence optical transient surveys, our understanding of the diversity of core-collapse supernovae has grown tremendously in the last decade.…
Radiative cooling in collisionally and photo ionized plasmas
M. L. Lykins, G. J. Ferland, Ryan L. Porter +3
We discuss recent improvements in the calculation of the radiative cooling in both collisionally and photo ionized plasmas. We are extending the spectral simulation code Cloudy so…
Variable Sodium Absorption in a Low-Extinction Type Ia Supernova
Joshua D. Simon, Avishay Gal-Yam, Orly Gnat +18
Recent observations have revealed that some Type Ia supernovae exhibit narrow, time-variable Na I D absorption features. The origin of the absorbing material is controversial, but…
