22 Orbits of Binaries Based on SOAR Speckle Observations: Systems with Intermediate Type Components*

The new observational data obtained during the 2020, 2021, 2022, 2023, and 2024 speckle runs with the 4.1-m Southern Astrophysical Research (SOAR) telescope located at Cerro Pachón (Chile) has been used to improve the orbits of the following 22 visual binaries with components of spectral types F and G, most of them from the main sequence: WDS 00271-0753 (A 431 AB), WDS 00463-0634 (HDS 101), WDS 03189-0101 (BU 1177), WDS 03596-1019 (HU 29), WDS 04502-3113 (B 1474), WDS 05276-2055 (SEE 53), WDS 05352-4657 (RST 141), WDS 06380-6132 (I 5 AB), WDS 07303-5657 (FIN 105), WDS 08075-1212 (A 2749), WDS 08331-2436 (BU 205 AB), WDS 11068-7050 (B 2006), WDS 13005-3330 (HDS 1824 Aa,Ab), WDS 13040-1738 (BU 798 AB), WDS 14565-3438 (I 227 AB), WDS 15548-6554 (NZO 65), WDS 17240-0921 (RST 3972 Aa,Ab), WDS 20073-5127 (RST 1059), WDS 20507-3116 (B 997), WDS 21395-0003 (BU 1212 AB), WDS 22586-4531 (HU 1335), WDS 23218-1217 (HU 95). In the cases that it was feasible, we have calculated the dynamical parallaxes and individual masses of the components and compared them with those in the literature.
