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"…

Luminous Type II Short-Plateau Supernovae 2006Y, 2006ai, and 2016egz: A Transitional Class from Stripped Massive Red Supergiants

Daichi Hiramatsu, D. Andrew Howell, Takashi J. Moriya +21

The diversity of Type II supernovae (SNe II) is thought to be driven mainly by differences in their progenitor's hydrogen-rich (H-rich) envelope mass, with SNe IIP having long plat…

Optical and Near-Infrared Observations of the Nearby Type Ia Supernova 2017cbv

Lingzhi Wang, Carlos Contreras, Maokai Hu +28

Supernova (SN) 2017cbv in NGC 5643 is one of a handful of type Ia supernovae (SNe~Ia) reported to have excess blue emission at early times. This paper presents extensive $BVRIYJHK_…

Carnegie Supernova Project: Classification of Type Ia Supernovae

Anthony Burrow, E. Baron, Chris Ashall +14

We use the spectroscopy and homogeneous photometry of 97 Type Ia supernovae obtained by the \emph{Carnegie Supernova Project} as well as a subset of 36 Type Ia supernovae presented…

Carnegie Supernova Project II: The slowest rising Type Ia supernova LSQ14fmg and clues to the origin of super-Chandrasekhar/03fg-like events

E. Y. Hsiao, P. Hoeflich, C. Ashall +34

The Type Ia supernova (SN Ia) LSQ14fmg exhibits exaggerated properties which may help to reveal the origin of the "super-Chandrasekhar" (or 03fg-like) group. The optical spectrum i…

The early discovery of SN 2017ahn: signatures of persistent interaction in a fast declining Type II supernova

L. Tartaglia, D. J. Sand, J. H. Groh +25

We present high-cadence, comprehensive data on the nearby () Type II SN 2017ahn, discovered within 1 day of explosion, from the very early phases after e…
