]]> RESUMEN
En este trabajo se obtienen nuevos parámetros orbitales para la binaria WDS 05386+3030 = BU 1240 AB debido a la existencia de residuos sistemáticos respecto a las últimas mediciones realizadas con posterioridad a 1985. Se utilizó una combinación de métodos gráneos y analíticos para el cálculo. La órbita preliminar fue mejorada usando el método de corrección diferencial de W. D. Heintz. Se obtuvo la masa. La naturaleza de las componentes C y D fue estudiada usando la fotometría BVIJHK y datos astrométricos y cinemáticos. Determinamos la naturaleza física de C y la óptica de D usando varios criterios.
ABSTRACT
New orbital parameters and masses for WDS 05386+3030 = BU 1240 AB were determined prompted by the large residuals seen in recent speckle measurements from 1985. A combined solution of graphical (to determine preliminary parameters) and analytical methods was used. The preliminary orbit was refined using the differential correction method by Heintz. The physical characteristics of the C and D components were studied using BVIJHK photometry, historical astrometry and kinematical data. Several criteria indicate a physical nature for C and an optical nature for D.

The author is specially grateful to Andreas Alzner for the transmission of his knowledge about orbital calculations; without his help and patience I would not have now enough skills and knowledge to calculate orbital parameters for visual double stars.
