Toomre diagram showing the kinematic distribution of our stars in the (V, $\sqrt{U^2+W^2}$) plane. The solid green curve represents a total space velocity of 210 km s^-1, approximately delimiting the thick-disk and halo populations (Gaia Collaboration 2023a), while the solid and dotted gray curves mark the 500 and 600 km s^-1 contours, respectively. Objects highlighted in orange correspond to those identified as having an extragalactic origin in this work. The target with the highest $\sqrt{U^2+W^2}$ value is HVS01.
