TRES Archives

TRES RV observations of HD 12800. We mark the dates of announcement (2022-06-13) and official retraction (2024-05-27) for the Gaia DR3 planet candidate. Our observations would have easily detected the RV signal expected from the Gaia DR3 orbital solution, and independently verify that the companion does not exist. While in this case the ultimate result is a non-detection, this nonetheless serves to demonstrate the value of intermediate-precision (≈10 m s−1 ) RV observations for the follow-up of Gaia astrometric exoplanet candidates. -- astro-ph.EP)

The detection of exoplanets using astrometry has long been an area of interest, but is fraught with challenges. The Gaia mission is fundamentally reshaping this field thanks to its unprecedentedly […]
