Equipotential surface of ∼795 stars within 50 pc of the Sun projected on the xy-plane in the Galactic potential. To make the potential more visible, we magnified the stellar masses by a factor 300. The Sun is indicated with the red dot in the middle of the figure. The red circle at ∼16 pc indicates the inner region for which the analysis in this paper is performed. This volume contains the 200 nearest stars (Torres et al. 2019b). The script to generate this image, plot_nearby_stars_equipotential_surface.py, and the required data (filename gaia_nearby_stars.amuse), are both available at figshare.
