Projections of the 6D Galactic kinematics of EROS J0032 compared to the young Tucana/Horologium, AB Doradus, and β Pictoris kinematic groups. EROS J0032 is presented by a violet diamond with associated error bars. The multiple points represent different possible values of the radial velocity (RV), ranging from –30 km s-1 to +30 km s-1 in increments of 5 km s-1. The young kinematic groups are designated in the figure legend. Top panels: projections in (UVW) Galactic velocity. The colored ellipses designate the 2σ dispersion of the average velocities of each group from Malo et al. (2013). EROS J0032 is most consistent with the Tuc/Hor and β Pic groups for RVs between ~5 and 10 km s-1. Bottom panels: projections of the (XYZ) Galactic distance. EROS J0032 is consistent with the distributions of all three young groups. For reference, we also plot the Galactic velocity space occupied by most young stars in the solar neighborhood as a dashed, grey box (Zuckerman & Song 2004).
