The DR14 APOGEE-TGAS catalogue: Precise chemo-kinematics in the extended solar vicinity

Abstract

We describe the DR14 APOGEE-TGAS catalogue, a new SDSS value-added catalogue that provides precise astrophysical parameters, chemical abundances, astro-spectro-photometric distances and extinctions, as well as orbital parameters for $\sim 30,000$ APOGEE-TGAS stars, among them $\sim 5,000$ high-quality giant stars within 1 kpc.

4 pages, 2 figures, to appear in the proceedings of the IAU Symposium 334 "Rediscovering our Galaxy", Potsdam, 10-14 July 2017, eds. C. Chiappini, I. Minchev, E. Starkenburg, M. Valentini. 2nd and final version contains a teaser of the abundance-space t-SNE results
