Abstract
The paper presents new orbit for two southern visual double stars BU 271 AB (ADS 14847 AB, CCDM 21198–2621) and BU 1004 AB (CCDM 04021–3429). Each orbit was determined by means of the Thiele-van den Bos method using three fundamental points and an areal constant value. A programme developed by Nys (1983) involving some conditions of validity of the method proposed by S. Arend and J. Dommanget was applied. Dynamical parallax and mass of each component was computed by means of the Baize & Romani (1946) method. Residual of observations were presented as well as the ephemerides.
