Relative astrometric orbit and selected predicted position for HD 57625 b. The position of the host star is marked by a yellow star, with a dashed line representing the line of nodes and a dotted line connecting the host star to the periastron. The coloured circles mark the predicted positions of the planetary companion at the epoch of our imaging observation (2024; blue), at the starting and final epochs of available RVs (2006 and 2019; red) and at the reference epochs for HIPPARCOS and Gaia DR3 (1991 and 2024; green).
