Masses of White Dwarf Binary Companions to Type Ia Supernovae Measured from Runaway Velocities
Evan B. Bauer, Vedant Chandra, Ken J. Shen +1
The recently proposed "dynamically driven double-degenerate double-detonation" (D6) scenario posits that Type Ia supernovae (SNe) may occur during dynamically unstable mass transfe…
Wide binaries from the H3 survey: the thick disk and halo have similar wide binary fractions
Hsiang-Chih Hwang, Yuan-Sen Ting, Charlie Conroy +8
Due to the different environments in the Milky Way's disk and halo, comparing wide binaries in the disk and halo is key to understanding wide binary formation and evolution. By usi…
Evidence from Disrupted Halo Dwarfs that -process Enrichment via Neutron Star Mergers is Delayed by Myrs
Rohan P. Naidu, Alexander P. Ji, Charlie Conroy +10
The astrophysical origins of -process elements remain elusive. Neutron star mergers (NSMs) and special classes of core-collapse supernovae (rCCSNe) are leading candidates. Due t…
The SNIa Runaway LP 398-9: Detection of Circumstellar Material and Surface Rotation
Vedant Chandra, Hsiang-Chih Hwang, Nadia L. Zakamska +12
A promising progenitor scenario for Type Ia supernovae (SNeIa) is the thermonuclear detonation of a white dwarf in a close binary system with another white dwarf. After the primary…
A 99-minute Double-lined White Dwarf Binary from SDSS-V
Vedant Chandra, Hsiang-Chih Hwang, Nadia L. Zakamska +12
We report the discovery of SDSS J133725.26+395237.7 (hereafter SDSS J1337+3952), a double-lined white dwarf (WD+WD) binary identified in early data from the fifth generation Sloan…
Searching for Low-mass Population III Stars Disguised as White Dwarfs
Vedant Chandra, Kevin C. Schlaufman
It is uncertain whether or not low-mass Population III stars ever existed. While limits on the number density of Population III stars with have bee…
