Spectroscopic follow-up of compact object binary candidates from Gaia DR3: White dwarfs, neutron stars, black holes, and the parallax zeropoint

Kareem El-Badry, David W. Latham, Hans-Walter Rix +12

Astrometry and radial velocities (RVs) from Gaia DR3 yielded orbits for hundreds of thousands of binary systems, including several samples proposed to contain black holes (BHs), ne…

A Galactic intermediate-mass stripped star with a Wolf-Rayet-like wind

Johanna Müller-Horn, Kareem El-Badry, Andreas A. C. Sander +17

Binary interaction in massive stars is expected to produce a large population of intermediate-mass (- M) envelope-stripped stars, yet such objects have remained elusi…

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

The paper describes the twentieth data release (DR20) of the Sloan Digital Sky Survey, providing over 3 million new optical spectra from the SDSS‑V Milky Way, Black Hole, and Local…

SpecFANN: Spectral Fitting via Artificial Neural Networks I. A deep learning based fastwind emulator and fitting suite

M. Abdul-Masih, C. Hawcroft, T. Lechien +14

The importance of massive stars cannot be overstated: they are powerful probes of the early universe, play a vital role in the chemical and mechanical evolution of their host envir…

The Chemical Homogeneity of Single-Lined Spectroscopic Binaries in Open Clusters

Amaya Sinha, Gail Zasowski, Natalie R. Myers +16

Using SDSS-V DR19 Milky Way Mapper APOGEE data, we measure the impact that close binarity has on surface chemistry across the Hertzsprung-Russell diagram in a broad set of abundanc…

Gaia Barium Dwarfs and Their Ostensibly Ordinary Counterparts

Param Rekhi, Sahar Shahaf, Sagi Ben-Ami +4

The recently identified Gaia population of main-sequence--white dwarf (MS+WD) binaries at separations of , often with moderate eccentricities, is not readily re…
