Speckle observations with PISCO in Calern (France)
Résumé
This paper presents orbits and masses for 22 visual double stars, partly derived using their last observations made with the speckle camera PISCO. For 13 of them we have determined their first time orbits. Masses were calculated from Hipparcos and Gaia parallaxes when available, and from dynamical parallaxes otherwise. They are compared with masses deduced from spectral types. Other physical and orbital properties are also considered.This paper presents orbits and masses for 22 visual double stars, partly derived using their last observations made with the speckle camera PISCO.
