Weighing the Darkness. II. Astrometric Measurement of Partial Orbits with Gaia
Over the course of several years, stars trace helical trajectories as they traverse across the sky due to the combined effects of proper motion and parallax. It is well known that the gravitational pull of an unseen companion can cause deviations to these tracks. Several studies have pointed out tha...
