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…

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…
