First orbits are derived for 12 new Hipparcos binary systems based on the precise speckle interferometric measurements of the relative positions of the components. The orbital periods of the pairs are between 5.9 and 29.0 yrs. Magnitude differences obtained from differential speckle photometry allow us to estimate the absolute magnitudes and spectral types of individual stars and to compare their position on the mass-magnitude diagram with the theoretical curves. The spectral types of the new orbiting pairs range from late F to early M. Their mass-sums are determined with a relative accuracy of 10-30%. The mass errors are completely defined by the errors of Hipparcos parallaxes. 1 Introduction Stellar masses can be derived only from the detailed studies of the orbital motion in binary systems. To test the models of stellar structure and evolution, stellar masses must be determined with ≈ 2% accuracy. Until very recently, accurate masses were available only for double-lined, detached eclipsing binaries [1].

(eds.) Data mining in the Spanish Virtual Observatory. Applications to Corot and Gaia. Mauro L´opez del Fresno1, Enrique Solano M´arquez1, and Luis Manuel Sarro Baro2 1 Spanish VO. Dep. Astrof´ısica. CAB (INTA-CSIC). P.O. Box 78, 28691 Villanueva de la Ca´nada, Madrid (Spain) 2 Departamento de Inteligencia Artificial. ETSI Inform´atica.UNED. Spain Abstract Manual methods for handling data are impractical for modern space missions due to the huge amount of data they provide to the scientific community. Data mining, understood as a set of methods and algorithms that allows us to recover automatically non trivial knowledge from datasets, are required. Gaia and Corot are just a two examples of actual missions that benefits the use of data mining. In this article we present a brief summary of some data mining methods and the main results obtained for Corot, as well as a description of the future variable star classification system that it is being developed for the Gaia mission. 1 Introduction Data in Astronomy is growing almost exponentially. Whereas projects like VISTA are pro- viding more than 100 terabytes of data per year, future initiatives like LSST (to be operative in 2014) and SKY (foreseen for 2024) will reach the petabyte level. It is, thus, impossible a manual approach to process the data returned by these surveys. It is impossible a manual approach to process the data returned by these surveys.
