Astrometry and Exoplanets: the Gaia Era, and Beyond
A. Sozzetti (INAF - Osservatorio Astronomico di Torino)
TL;DR
This paper reviews Gaia's micro-arcsecond astrometry's potential to revolutionize exoplanet science, discusses necessary follow-up observations, and explores future astrometric facilities' roles in planetary system studies.
Contribution
It provides a comprehensive overview of Gaia's impact on exoplanet research and discusses future directions in astrometric observations beyond Gaia.
Findings
Gaia will significantly advance exoplanet detection and characterization.
Follow-up observations are crucial for maximizing Gaia data's scientific return.
Next-generation astrometric facilities will play a key role in future planetary system studies.
Abstract
The wealth of information in the Gaia catalogue of exoplanets will constitute a fundamental contribution to several hot topics of the astrophysics of planetary systems. I briefly review the potential impact of Gaia micro-arsec astrometry in several areas of exoplanet science, discuss what key follow-up observations might be required as a complement to Gaia data, and shed some light on the role of next generation astrometric facilities in the arena of planetary systems.
