Measuring The Mass-Radius Relation of White Dwarfs Using Wide Binaries
Stefan Arseneau, Vedant Chandra, Hsiang-Chih Hwang +10
Measuring the mass-radius relation of individual white dwarfs is an empirically challenging task that has been performed for only a few dozen stars. We measure the white dwarf mass…
The Three-Phase Evolution of the Milky Way
Vedant Chandra, Vadim A. Semenov, Hans-Walter Rix +6
We illustrate the formation and evolution of the Milky Way over cosmic time, utilizing a sample of 10 million red giant stars with full chemodynamical information, including metall…
Discovery of a Proto-White Dwarf with a Massive Unseen Companion
Gautham Adamane Pallathadka, Vedant Chandra, Nadia L. Zakamska +8
We report the discovery of SDSS~J022932.28+713002.7, a nascent extremely low-mass (ELM) white dwarf (WD) orbiting a massive ( at 2 confidence) companion with a per…
AspGap: Augmented Stellar Parameters and Abundances for 23 million RGB stars from Gaia XP low-resolution spectra
Jiadong Li, Kaze W. K. Wong, David W. Hogg +2
We present AspGap, a new approach to infer stellar labels from low-resolution Gaia XP spectra, including precise [/M] estimates for the first time. AspGap is a neural-network ba…
Extending the Chemical Reach of the H3 Survey: Detailed Abundances of the Dwarf-galaxy Stellar Stream Wukong/LMS-1
Guilherme Limberg, Alexander P. Ji, Rohan P. Naidu +10
We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < \rm[Fe/H] \lesssim -…
The fastest stars in the Galaxy
Kareem El-Badry, Ken J. Shen, Vedant Chandra +18
We report a spectroscopic search for hypervelocity white dwarfs (WDs) that are runaways from Type Ia supernovae (SNe Ia) and related thermonuclear explosions. Candidates are select…
