The Galactic disk structure revealed by Gaia XP spectra
Zhenkang Tang, Jianhui Lian, Jialong Zhou +1
The spatial structures of chemical populations constrain Galactic disk evolution and its underlying physical processes. Gaia XP spectra provide one of the largest spectroscopic sam…
Mass-dependent multiplicity fraction in low mass stars revealed by Gaia astrometry
Ben Pennell, Hans-Walter Rix, Kareem El-Badry +3
Stellar multiplicity at different orbital periods is probed by different techniques: radial velocities at the shortest periods, direct imaging at the longest, and astrometry in bet…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
A Probabilistic Framework for Population Studies of the Solar Neighborhood: Application to SDSS-V and Gaia
Ilija Medan, Keivan G. Stassun, Zachary Way +8
Studies of the Solar Neighborhood require spectroscopic follow-up of stars identified in astrometric surveys to fully characterize their physical properties. The SDSS-V Solar Neigh…
oMEGACat. X. Shedding light on the disrupted dwarf galaxy of Omega Centauri
Stefano Souza, Nadine Neumayer, Anil C. Seth +15
Omega Centauri (Cen) is the most massive and chemically complex star cluster in the Milky Way and is widely regarded as the surviving nuclear star cluster of an accreted dwarf…
Stellar Parameters of BOSS M dwarfs in SDSS-V DR19
Dan Qiu, Jennifer A. Johnson, Chao Liu +15
We utilized the Stellar LAbel Machine (SLAM), a data-driven model based on Support Vector Regression, to derive stellar parameters ([Fe/H], , and ) for SDSS-V…
The Silent Majority: The Interacting Post-Common-Envelope Binaries Underlying Cataclysmic Variables
Yarin Meir Shani, Na'ama Hallakoun, Sagi Ben-Ami +4
We analyze the orbital period distribution of post-common-envelope white-dwarf-main-sequence (WDMS) binaries by cross-matching the new spectroscopic Gaia DR3 WDMS catalog with TESS…
Dormant black hole candidates from Gaia DR3 summary diagnostics
Johanna Müller-Horn, Hans-Walter Rix, Kareem El-Badry +4
We present a rigorous identification of candidates for dormant black holes (BHs) and neutron stars (NSs) in binaries using summary statistics from Gaia DR3, rather than full orbita…
Millions of Main-Sequence Binary Stars from Gaia BP/RP Spectra
Jiadong Li, Hans-Walter Rix, Yuan-Sen Ting +6
We present the main-sequence binary (MSMS) Catalog derived from Gaia Data Release 3 BP/RP (XP) spectra. Leveraging the vast sample of low-resolution Gaia XP spectra, we develop a f…
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…
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…
