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…

The Red Supergiant Binary Fraction of the Large Magellanic Cloud

Kathryn F. Neugent, Emily M. Levesque, Philip Massey +2

The binary fraction of unevolved massive stars is thought to be 70-100% but there are few observational constraints on the binary fraction of the evolved version of a subset of the…

A search for strong magnetic fields in massive and very massive stars in the Magellanic Clouds

S. Bagnulo, G. A. Wade, Y. Naze +13

Despite their rarity, massive stars dominate the ecology of galaxies via their strong, radiatively-driven winds throughout their lives and as supernovae in their deaths. However, t…
