High-contrast imaging of 18 compact-object binaries yields no robust tertiary detections and rules out main-sequence tertiaries at projected separations greater than 500 au for Gaia systems and 2000 au for BH LMXBs.

Reconstruction of GRO J1655-40, SAX J1819.3-2525 and 4U 1543-47 requires CE efficiencies α_0.5U ≳6.7, α_U ≳4.2, α_H ≳1.7 with no solutions below unity, implying need for additional energy or formalism changes plus natal kicks ≳50 km/s for 4U 1543-47.
SKA+VLBI will deliver microarcsecond astrometry, polarimetry, and rapid multi-frequency imaging to track jets and accretion in X-ray binaries on AU scales.
This perspective paper outlines expected advances in studying accretion and jets in compact object binaries using the SKA's improved sensitivity and resolution.

Searching for the Third Wheel: High-Contrast Imaging Constraints on Tertiaries to Black Hole and Neutron Star Binaries
High-contrast imaging of 18 compact-object binaries yields no robust tertiary detections and rules out main-sequence tertiaries at projected separations greater than 500 au for Gaia systems and 2000 au for BH LMXBs.
