Observabilite Par HIPPARCOS des Etoiles Doubles Spectroscopiques
Abstract
Spectroscopic binaries have been proposed for observation by the astrometric satellite HIPPARCOS. But their admittance in the Input Catalogue is subordinated to the behaviour of their photocenters of which the orbital oscillation on the sky must remain inside narrow limits bound to the accuracy of the HIPPARCOS observation technique. It is shown that at least 90% of the known spectroscopic orbital binaries fulfil this requirement.
