2019 SOAR speckle interferometry of binary stars
Listed in IVOA Registry (Virtual Observatory)
The results of speckle-interferometric observations at the 4.1m Southern Astrophysical Research Telescope in 2019 are given, totaling 2555 measurements of 1972 resolved pairs with separations from 15mas (median 0.21") and magnitude difference up to 6mag, and non-resolutions of 684 targets.
Description
We resolved for the first time 90 new pairs or subsystems in known binaries. This work continues our long-term speckle program.
Its main goal is to monitor orbital motion of close binaries, including members of high-order hierarchies and Hipparcos pairs in the solar neighborhood. We give a list of 127 orbits computed using our latest measurements. Their quality varies from excellent (25 orbits of grades 1 and 2) to provisional (47 orbits of grades 4 and 5).
