Comparaison des théories des mouvements des satellites de Saturne avec des observations de phénomènes.
Abstract
As every fifteen years, phenomena occurred among the Saturnian system of satellites in 1995. Because the Sun and Earth passed through the equatorial plane of the planet which is close to the orbital planes of its main satellites, eclipses and occultations by Saturn occur as well as eclipses and occultations of a satellite by another. These phenomena lead to accurate astrometric observations; therefore the authors organized an international campaign to observe them. At the present time, they have collected one hundred of such mutual events and have analyzed half of them. In this preliminar analysis they got precisions of 0″048 by comparing the observed data either with the Dourneau's theory or with the Vienne and Duriez TASS theory.
