Identified companion candidates to K-type Sco-Cen members. Members of the YSES subsample are highlighted by the black outline around the marker. The orange star highlights the brown dwarf companion TYC 8252-533-1 B that is analyzed in Sect. 4.1. The apparent Gaia G band magnitude is presented as a function of projected separation in arcseconds. Due to the PSF halo of the primary, the detectable magnitude threshold increases with larger separations from the host. This area of reduced sensitivity is indicated by the red, dashed triangle. The gray-shaded region represents the field of view of the SPHERE/IRDIS detector.
