RESUMEN

Se presentan los elementos orbitales de sistemas binarios WDS 03494-1956 = RST 2324, WDS 03513+2621 = A 1830, WDS 04093-2025 = RST 2333, WDS 06485-1226 = A 2935, WDS 07013-0906 = A 671 y WDS 18323-1439 = CHR 73. Se derivan las masas individuales y las paralajes dinámicas para todos los sistemas con excepción de WDS 18323-1439.

 

ABSTRACT

Preliminary orbital elements of binary systems WDS 03494-1956 = RST 2324, WDS 03513+2621 = A 1830, WDS 04093-2025 = RST 2333, WDS 06485-1226 = A 2935, WDS 07013-0906 = A 671, and WDS 18323-1439 = CHR 73 are presented. For all systems but WDS 18323-1439 the individual masses and dynamical parallaxes are derived.

Key Words: Binaries: Visual — Stars: Distances — Stars: Fundamental parameters — Stars: Masses.
