Carnegie Supernova Project-II: Near-infrared Spectroscopic Diversity of Type II Supernovae

S. Davis, E. Y. Hsiao, C. Ashall +24

We present near-infrared (NIR) spectra of Type II supernovae (SNe II) from the Carnegie Supernova Project-II (CSP-II), the largest such dataset published to date. We iden…

Comparison of the optical light curves of hydrogen-rich and hydrogen-poor type II supernovae

P. J. Pessi, G. Folatelli, J. P. Anderson +12

Type II supernovae (SNe II) show strong hydrogen features in their spectra throughout their whole evolution while type IIb supernovae (SNe IIb) spectra evolve from dominant hydroge…

SN 2017gmr: An energetic Type II-P supernova with asymmetries

Jennifer E. Andrews, D. J. Sand, S. Valenti +77

We present high-cadence ultraviolet (UV), optical, and near-infrared (NIR) data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through the first 180 days…

A Physical Basis for the H-band Blue-edge Velocity and Light-Curve Shape Correlation in Context of Type Ia Supernova Explosion Physics

C. Ashall, P. Hoeflich, E. Y. Hsiao +17

Our recent work demonstrates a correlation between the high-velocity blue edge, , of the iron-peak Fe/Co/Ni -band emission feature and the optical light curve shape of…

Gas phase SiO in the circumstellar environment of the recurrent nova T Coronae Borealis

A. Evans, Ya. V. Pavlenko, D. P. K. Banerjee +9

We report the discovery of the diatomic molecule SiO in the gas phase in the environment of the recurrent nova T Coronae Borealis. While some of the SiO is photospheric, a substant…

Carnegie Supernova Project-II: Using Near-Infrared Spectroscopy to determine the location of the outer Ni in Type Ia Supernovae

C. Ashall, E. Y. Hsiao, P. Hoeflich +17

We present the -band wavelength region of thirty post-maximum light near-infrared (NIR) spectra of fourteen transitional and sub-luminous type Ia supernovae (SNe Ia), extending…
