Yes, an example is "Local stellar kinematics from Hipparcos data" [0]. Afaict: stars have color (red or blue shift) which represents relative motion; Hipparcos is a large large dataset from an eponymous satellite; fancy math determines relative motion based on position and inferred distance. 0. https://arxiv.org/abs/astro-ph/9710077 https://arxiv.org/abs/astro-ph/9710077
