Gaia's revolution in stellar variability
L. Eyer, L. Rimoldini, L. Rohrbasser +15
Stellar variability studies are now reaching a completely new level thanks to ESA's Gaia mission, which enables us to locate many variable stars in the Hertzsprung-Russell diagram…
Multivariate Time-series Analysis of Variable Objects in the Gaia Mission
Laurent Eyer, Maria Süveges, Joris De Ridder +5
In astronomy, we are witnessing an enormous increase in the number of source detections, precision, and diversity of measurements. Additionally, multi-epoch data is becoming the no…
ESA Voyage 2050 white paper -- Faint objects in motion: the new frontier of high precision astrometry
F. Malbet, U. Abbas, J. Alves +28
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Triage of Astrometric Binaries - how to find triple systems and dormant black-hole secondaries in the Gaia orbits
Sahar Shahaf, Tsevi Mazeh, Simchon Faigler +1
Preparing for the expected wealth of Gaia detections, we consider here a simple algorithm for classifying unresolved astrometric binaries with main-sequence (MS) primary into three…
