star streaming
Quick Summary
Star streaming refers to the real or apparent systematic drift of stars. This phenomenon is observed when astronomers analyze the motions of stars within our galaxy, the Milky Way.12
Stellar motions can be determined by measuring a star's proper motion (its movement across the line of sight) and its radial velocity (its movement towards or away from us). By studying these motions, astronomers have identified that stars don't move entirely at random. Instead, they exhibit a preferential direction of motion, known as stream motion, which is somewhat confined to the galactic plane and the direction of galactic rotation. This indicates a commonality of motion among groups of nearby stars.2

…he discovered the phenomenon of star streaming—i.e., that the peculiar motions (motions of individual stars relative to the mean motions of their neighbours) of stars are not random but are grouped around two opposite, preferred directions in space. Many later investigations of the distances and spatial arrangement of the stars…

…successfully explained this phenomenon (called star streaming) as an effect of rotation of the Milky Way and thus became the first to offer substantial evidence that the Galaxy rotates. This theory was definitely proved soon after by Jan Oort of the Netherlands.
