Abstract

We propose here a methodology in which by using large samples of homogeneous optical spectra one can obtain a spectral type specific spectral index, which in combination with unrivalled kinematic information from Gaia allows one to identify ultracool subdwarf candidates. We also discuss the reasoning for this method, intended for use alongside existing photometry and astrometry in the Gaia era.
