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...

We present relative astrometric and photometric measurements of visual binaries made in 2009-2010, with the 76-cm refractor of Côte d'Azur Observatory and a pair ofsensitive EMCCD ANDOR cameras. Ourobserving list consists of optical pairs and binaries whoseorbital motion is still uncertain. Three differenttechniques were used for obtaining...

We present relative astrometric measurements of visual binaries, made in 2015-2016 with the speckle camera PISCO at the 1-m Epsilon telescope of the C2PU facility (Observatoire de la Côte d'Azur, Calern site). Our observing list contains orbital couples as well as binaries whose motion is still uncertain. From our 1233 observations of 1173...
