The Need for Infrared Astrometry of Brown Dwarfs in the Post-Gaia Era

Brown dwarf research in the next decade will be reliant on extending high- precision astrometry in wavelength and temporal coverage. Future astrometry will enable measures of the low-mass cutoff of star formation, allow for the discovery of cold brown dwarf analogs to cold (exo)planets, and enable mass measurements for single and binary systems .
