Compilation of orbits based on the 6D positions of the members of the Helmi streams. These orbits have been integrated for 100 Myr backwards and forward in time. The position of the Sun is illustrated with a red star, the Galactic centre is at (X, Z)=(0, 0) in this frame. The trajectories of stars that currently have V_Z >  0 are coloured black, while those with V_Z <  0 are shown in blue. Close to the solar position, the majority of the Helmi streams’ members move perpendicular to the plane of the disc, and are close to pericentre.
