Astrometry as a Tool for Discovering and Weighing Faint Companions to Nearby Stars [PDF]

arXiv
This tutorial covers the use of absolute astrometry, in particular from the combination of the Hipparcos and Gaia missions, to identify faint companions to nearby stars and to measure the masses and orbits of those companions. Absolute astrometry has been used with increasing success to discover new planets and brown dwarfs and to measure masses and ...
