Confirmation of co-moving star pairs identified in Gaia DR1

Recently, Oh et al published "Co-moving stars in Gaia DR1" ( which identified over 13000 co-moving star pairs in Gaia DR1 based upon their proper motions and parallaxes. Some of the pairs form larger groups (e.g., they recovered the Pleiades).

About 350 of these pairs of stars are also in the Cannon 1.3 table. Oh et al found a similar sized overlap with RAVE. We would be able to use the GALAH results to investigate the 3D space motions and chemistry of these stars to identify those stars which true binaries and clusters. Most of the pairings that are also in GALAH are in the Pleiades.
