Abstract:
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.
Description:
The orbital elements calculated for the 22 binaries are listed in
Table 1.
Table 2 shows astrometric measurements made in 2016-2022 with the
PISCO speckle camera at Calern Observatory and the residuals with the
orbit calculated in this work and with the previous orbit, if
applicable.
