Recalculated Orbits of 8 Double Stars

Abstract

The authors present new orbital elements for the following pairs: ADS 1227 ADS 3317, ADS 8128, ADS 8239, ADS 8242, ADS 8539, ADS 8949 and McA 61. Individual masses for these pairs are also calculated. For the pairs ADS 8128, ADS 8239, ADS 8539 and ADS 8949 calculated parallaxes are in accordance with the corresponding parallaxes of the Hipparchos Program. Autori ovog rada daju nove putanjske elemente za sledece dvojne zvezde: ADS 1227, ADS 3317, ADS 8128, ADS 8239, ADS 8242, ADS 8539, ADS 8949 i McA 61. Za parove ADS 8128, ADS 8239, ADS 8539 i ADS 8949 izracunate su i paralakse koje se dobro slazu sa rezultatima Hipparchos programa, kao i pojedinacne mase sistema.
