cds-question@unistra.frmultiple-starsastrometryvisible-astronomyinfrared-photometrystellar-massesstellar-spectral-typesThe orbits of eight systems with low-mass components (HIP14524, HIP16025, HIP28671, HIP46199, HIP47791, HIP60444, HIP61100, and HIP73085) are presented. Speckle interferometric data were obtained at the 6m Big Telescope Alt-azimuth Special Astrophysical Observatory of the Russian Academy of Sciences (BTA SAO RAS) from 2007 to 2019. New data, together with measures already in the literature, made it possible to improve upon previous orbital solutions in six cases and to construct orbits for the first time in the two remaining cases (HIP14524 and HIP60444). Mass sums are obtained using both Hipparcos and Gaia parallaxes, and a comparison with previously published values is made. Using the Worley & Heintz criteria, the classification of the orbits constructed is carried out.2020AJ....159..266Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/266CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+, 2001-2014)III/22 : Rotation of Evolving A and F Stars (Danziger+ 1972)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/AJ/106/1639 : Speckle observations of binary stars (McAlister+ 1993)J/AJ/119/3084 : ICCD speckle obs. of binary stars.
