Radial velocity data characterizes long-period companions, suggesting insights into planetary nature.
Key Points
This work aims to develop a model that combines astrometric data with radial velocity measurements to constrain the true masses of long-period companions.
Combined analysis of Hipparcos and Gaia astrometric data with radial velocity.
Application of proper motion anomalies technique for orbital inclination determination.
Re-analysis of previously unstudied targets using the new approach.
Sensitivity curve analysis to verify parameters.
HD 5388 b and HD 6718 b classified as planets with approximate masses of 3.2 M_Jup and 2.4 M_Jup.
HD 141937 b is likely a planet, but true mass remains uncertain.
HD 16760 b identified as a brown dwarf with a probable second companion.
30 Ari B b falls within the stellar regime, with potential companion affecting reliability.
Orbital inclinations determined for HD 148427 b, HD 96127 b, and HIP 65891 b.
