Kinematics of Fainst Stars of the Sco-Cen Association According to Gaia Catalog

Abstract

The kinematic properties of the Sco-Cen association have been studied using the spatial velocities of young stars. New kinematic age estimates for the three components of the association with the age of UCL and LCC being $$17.7 \pm 2.4$$ Myr and the age of US being $$6.4 \pm 1.7$$ Myr have been obtained. The parameters of the residual velocities US, UCL, and LCC ellipsoid have been estimated.
