| Summary: | Within a 200 pc sphere around the Sun, we search for the Hyades tidal tails in the <i>Gaia<i/> DR2 dataset.<i>Methods<i/>. We used a modified convergent-point method to search for stars with space velocities close to the space velocity of the Hyades cluster.<i>Results<i/>. We find a clear indication for the existence of the Hyades tidal tails, a leading tail extending up to 170 pc from the centre of the Hyades with 292 stars (36 contaminants), and a trailing tail up to 70 pc with 237 stars (32 contaminants). A comparison with an N-body model of the cluster and its tails shows remarkably good coincidence. Five white dwarfs are found in the tails. |
