Abstract

We present new speckle measurements of the position of Linus, the satellite of the asteroid (22) Kalliope, obtained at the 1 m Centre Pédagogique Planètes et Univers -Epsilon telescope on the Plateau de Calern , France. Observations were made in the visible domain with the speckle camera Pupil Interferometry Speckle camera and COronagraph. We obtained 122 measurements in February–March 2022 and April 2023, with a mean uncertainty close to 10 milliarcsec on the angular separation. [ABSTRACT FROM AUTHOR]

Abstract

Revised orbits and system masses are presented for the following 6 visual double stars: WDS 01259-4754 (RST 33), WDS 16057-3252 (SEE 264), WDS 17575+1058 (BU 1299 AB), WDS 19471-0809 (A 108), WDS 21000+4004 (KUI 103), and WDS 22329+5348 (KUI 112 Aa). In all of these systems, at least one component is of the late-type and the latest observations were made using speckle or CCD techniques. Total system masses were calculated in each case from the orbital period and semiaxis major together with the updated Hipparcos parallax, except in the cases for which there were no Hipparcos data or when these values were not precise.
