The Absolute Magnitudes of 1991T-like Supernovae
M. M. Phillips, C. Ashall, Christopher R. Burns +20
1991T-like supernovae are the luminous, slow-declining extreme of the Branch shallow-silicon (SS) subclass of Type Ia supernovae. They are distinguished by extremely weak Ca II H &…
SN 2013ai: a link between hydrogen-rich and hydrogen-poor core-collapse supernovae
S. Davis, P. J. Pessi, M. Fraser +33
We present a study of optical and near-infrared (NIR) spectra along with the light curves of SN 2013ai. These data range from discovery until 380 days after explosion. SN 2013ai is…
Strong Near-Infrared Carbon Absorption in the Transitional Type Ia SN 2015bp
S. D. Wyatt, D. J. Sand, E. Y. Hsiao +20
Unburned carbon is potentially a powerful probe of Type Ia supernova (SN) explosion mechanisms. We present comprehensive optical and near-infrared (NIR) data on the "transitional"…
Carnegie Supernova Project-II: A new method to photometrically identify sub-types of extreme Type Ia Supernovae
C. Ashall, J. Lu, C. Burns +16
We present a new method to photometrically delineate between various sub-types of type Ia supernovae (SNe Ia). Using the color-stretch parameters, or , and the tim…
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…
