Micrometric measures and orbits of southern visual double stars
Abstract
525 measures of 213 visual double stars have been made using the 26.5-inch (67-cm) Innes telescope in Johannesburg and the Repsold micrometer between 2008.375 and 2008.419, 2010.608 and 2010.652, and 2013.663 and 2013.712. A comparison with known orbits is made. Revised orbits are presented for WDS 01061-4643 (SLR 1), WDS 12415-4858 (HJ 4539), WDS 16253-4909 (COO 197) and WDS 16425-3705 (R 283).
