Structure of the outer galactic disk with Gaia DR2
In this work, we study the structure of the outer Galactic disk up to Galactocentric distance R=20 kpc. We use the Gaia DR2 data on which we apply a deconvolution technique in the parallax errors. We recover for each line of sight the distribution of stars as a function of distance, which we use to construct density maps, that we analyze. We study
