Identifying Binary Stars in the HARPS Database with Gaia Astrometry, Photometry, and Radial Velocities.

WANG L.

Abstract (from CDS):

I identify binaries among stars monitored by the High-Accuracy Radial velocity Planetary Searcher spectrograph using radial velocities (RVs), Gaia astrometry, and photometry. Out of 141 Gaia-selected targets, I identify 68 photometric binaries and report RV variability in 138 stars. Gaia Data Release 4 (DR4) is expected in mid 2026, and these results provide candidates well-suited for analysis with Gaia DR4's non-single star astrometric solutions.
