Stellar parameters and abundances for 3.2 million DESI DR1 spectra using machine learning
Nagaraj Vernekar, Michael Hayden, Sara Lucatello
We present a machine-learning pipeline for determining stellar parameters and chemical abundances from spectra observed by the Dark Energy Spectroscopic Instrument (DESI). Building…
A Detailed Model Atmosphere Analysis of Cool White Dwarfs in DESI DR1
Mukremin Kilic, Pierre Bergeron, Simon Blouin +9
We present a detailed model atmosphere analysis of cool white dwarfs in the Dark Energy Spectroscopic Instrument Data Release 1 (DESI DR1). Our sample includes 25,642 unique target…
The dawn is quiet II: Gaia XP constraints on the Milky Way's proto-Galaxy from very metal-poor MDF tails
Boquan Chen, Matthew D. A. Orkney, Yuan-Sen Ting +1
The earliest phase of the Milky Way's evolution involved a transition from a dispersion-supported proto-galaxy to a rotationally supported disk. A key chemical signature of this tr…
Discovery of A Starburst in the Early Milky Way at [Fe/H]
Boquan Chen, Matthew Orkney, Yuan-Sen Ting +1
We present an analysis of very metal-poor (VMP) and metal-poor stars () in the Gaia BP/RP or XP catalog, which reveals two distinct metallicity distri…
