Query: Wide Binaries in Tycho-Gaia II: Metallicities, Abundances, and Prospects
  for Chemical Tagging   From our recent catalog based on the first Gaia data release (TGAS), we
select wide binaries in which both stars have been observed by the Radial
Velocity Experiment (RAVE) or the Large Sky Area Multi-Object Fibre
Spectroscopic Telescope (LAMOST). Using RAVE and LAMOST metallicities and RAVE
Mg, Al, Si, Ti, and Fe abundances, we find that the differences in the
metallicities and elemental abundances of components of wide binaries are
consistent with being due to observational uncertainties, in agreement with
previous results for smaller and more restricted samples. The metallicity and
elemental abundance consistency between wide binary components presented in
this work confirms their common origin and bolsters the status of wide binaries
as "mini-open clusters." Furthermore, this is evidence that wide binaries are
effectively co-eval and co-chemical, supporting their use for e.g.,
constraining age-activity-rotation relations, the initial-final mass relation
for white dwarfs, and M-dwarf metallicity indicators. Additionally, we
demonstrate that the common proper motion, common parallax pairs in TGAS with
the most extreme separations (s $\gtrsim$ 0.1 pc) typically have inconsistent
metallicities, radial velocities or both and are therefore likely to be
predominantly comprised of random alignments of unassociated stars with similar
astrometry, in agreement with our previous results. Finally, we propose that
wide binaries form an ideal data set with which to test chemical tagging as a
method to identify stars of common origin, particularly because the stars in
wide binaries span a wide range of metallicities, much wider than that spanned
by nearby open clusters.
