Realizing the Promise of High-Contrast Imaging: More Than 100 Gas-Giant Planets with Masses, Orbits, and Spectra Enabled by Gaia+WFIRST Astrometry

2019

This white paper identifies absolute astrometry by Gaia and WFIRST-WFI as a powerful complement to ground-based imaging. A shallow, full-sky WFIRST survey could calibrate Gaia's data products and discover and weigh ~160 planets that can be imaged by 30-m telescopes.
