A "blue ring nebula" surrounding a thousands of years old stellar merger
Keri Hoadley, Christopher Martin, Brian D. Metzger +7
Stellar mergers are a brief-lived but common phase in the evolution of binary star systems. Among the many astrophysical implications of these events include the creation of atypic…
New Insights into Classical Novae
Laura Chomiuk, Brian D. Metzger, Ken J. Shen
We survey our understanding of classical novae: non-terminal, thermonuclear eruptions on the surfaces of white dwarfs in binary systems. The recent and unexpected discovery of GeV…
Distribution of Si II 6355 Velocities of Type Ia Supernovae and Implications for Asymmetric Explosions
Keto D. Zhang, WeiKang Zheng, Thomas de Jaeger +7
The ejecta velocity is a very important parameter in studying the structure and properties of Type Ia supernovae (SNe Ia). It is also a candidate key parameter in improving the uti…
SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features
Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64
We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…
Direct evidence for shock-powered optical emission in a nova
Elias Aydi, Kirill V. Sokolovsky, Laura Chomiuk +39
Classical novae are thermonuclear explosions that occur on the surfaces of white dwarf stars in interacting binary systems (Bode & Evans 2008). It has long been thought that the lu…
Manganese Indicates a Transition from Sub- to Near-Chandrasekhar Type Ia Supernovae in Dwarf Galaxies
Mithi A. C. de los Reyes, Evan N. Kirby, Ivo R. Seitenzahl +1
Manganese (Mn) abundances are sensitive probes of the progenitors of Type Ia supernovae (SNe). In this work, we present a catalog of manganese abundances in dwarf spheroidal satell…
