The GAIA astrometric mission of ESA will be very efficient in discovering binary and multiple stars with any orbital period, from minutes to millions of years. The main parameters of the revised mission design are presented. Next we estimate the fraction of binary stars discovered by means of astrometry, photometry and on-board spectroscopy. Finally we summarize observations that confirm the ability to measure physical parameters like masses, radii and spectroscopic distance from GAIA data alone. GAIA will fly only in 2010, but the radial velocity experiment (RAVE) has started this year. We show that its spectroscopic observations have the capacity to discover a large fraction of so far unknown binary systems.

Resumen

Resumen

La misión astrométrica GAIA de la ESA va a ser muy eficiente para descubrir estrellas dobles y múltiples de cualquier período, desde minutos hasta millones de años. Se presentan los parámetros principales del diseño revisado de la misión. Seestima la fracción de binarias que serán descubiertas mediante astrometría, fotometría y espectroscopía a bordo. Finalmente, se resumen las observaciones que confirman la posibilidad de medir parámetros como las masas, los radios y las distancias espectroscópicas exclusivamente a partir de datos de GAIA. GAIA no volará sino hasta 2010, pero el experimento de velocidades radiales (RAVE) ya comenzó este año. Mostramos que las observaciones espectroscópicas de éste son capaces de descubrir una gran parte de los sistemas binarios aún desconocidos.
