The BeStars project contains (1) the complete catalogue of classical Be stars, BeSC, with some of their fundamental stellar parameters, and (2) a database, BeSS, which assembles classical Be star spectra obtained by professional and amateur astronomers at any wavelength, epoch, and spectral resolution.
The principal research topics of the GEPI (Galaxy - Star - Physics - Instrumentation) Laboratory are the formation and evolution of stars in our Galaxy as well as in numerous other galaxies, which constitute the luminous matter (baryonic matter) component of the Universe. This research calls upon many disciplines, from chemistry to physics, from instrumentation to data-processing engineering, and from project management to financial management within an international framework.
The IMCCE is a research institute of the Paris Observatory, associated with the CNRS (UMR8028), whose work concerns mainly the dynamic and planetologic studies of the bodies of the solar system and of the terrestrial environment: planets, natural satellites, asteroids, comets, meteoroids and space debris. The IMCCE, through its VO Solar System Portal, places at the disposal of the Virtual observatory its knowledge and its expertise which concern the dynamics and the physics of the bodies of the solar system through databases, ephemeris computation services, tools of simulation, and numerical computation services fully compliant with the interoperability concept of the Virtual Observatory.
The main activity at Nançay is the development and application of new radio techniques to fundamental research in astrophysics and astronomy. A number of instruments are operated on behalf of researchers in France and worldwide to conduct scientific programmes of observation of the Universe, including the nearby Earth-Space environment, the study of the Sun and the solar system, and the study of distant stars and galaxies in the Universe.
VOPSAT is a set of southern sky digital surveys based on ESO-R, SRC-J and POSS1-E atlases. The plates have been digitized with the MAMA microdensitometer with a resolution of 0.7 arc-sec. Pixel resampling will allow mosaicing neighbouring Schmidt fields up to hundreds of square degrees.
