    It seems a fragment of the original star catalogue of #Hipparcos may have been discovered. Would be a great discovery, marking a milestone of the beginning of quantitative #Astronomy . Another #Palimpsest for the win!

    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.
