Constraints for the orbital #inclination and the true mass of long-period single companions.
This work illustrates how #Gaia and #Hipparcos allow for the orbital properties and masses of long-period RV companions to be further constrained.
The first constraints for nearby long-period #planets from Gaia have started getting published.
