Evidence suggesting an interaction between disk stream Theia 368 (in green) and Sco-Cen (in gray). The black arrows show a running median of the stream’s motion relative to its bulk motion, depicted by the purple arrow. The relative motion is scaled up by a factor of 30 compared to the bulk motion to highlight their distribution properly; see the legend on the top left for a size comparison. The relative motions across Theia 368 highly correlate with the stream’s interaction time with Sco-Cen; i.e., the further inside Theia 368’s members are found in Sco- Cen, the more drastically their motions have been altered.
