Abstract

The large Galactic coverage of spectroscopic stellar surveys provides a perfect testbench for studying the chemo-kinematic properties of our Galaxy and allows us to check the validity of chemo-dynamical models of the Milky Way. In this project, we compare APOGEE data to the chemo-dynamical model of Minchev et al. (2013, 2014) using dedicated mock observations. We focus on [Fe/H] abundance and its radial and azimuthal distribution, which we find to show different behaviours in the inner and outer disc. We also discuss the time evolution of the model (using several snapshots), and how the azimuthal [Fe/H] variations depend on stellar age. This analysis is a first step towards understanding the measured azimuthal abundance variations in the Galactic disc
