Values of the semi-major axis a and mass ratio q compatible with the observed value of PMa, RUWE, and scatter in RVs for a close companion to HIP 60855. The upper panel shows the values obtained only using the PMa; the middle panel those obtained also considering the RUWE, and the bottom panel the solutions compatible with all data. Dashed lines mark the semi-major axis corresponding to a projected separation of 0.12 and 1 arcsec, the approximate limit for detection using high contrast imaging (HCI) and Gaia, respectively. This particular companion is not expected to be detectable as a visual binary.
