Prediction of stellar occultations by satellite of asteroids
2004Our group is working on the orbit determination of asteroid satellites on the last four years gathering data recorded with several AO systems. Based upon our observations, we focused specifically on models for (22) Kalliope, (121) Hermione, (45) Eugenia and (90) Antiope systems characterizing accurately their dynamical and physical properties (Marchis ...

Asteroid astrometry with Gaia: stellar occultations and beyond
2017The first data release of star astrometry by Gaia (Sept. 2016) has given an anticipation of the mission capabilities. By providing positions with uncertainties at the level of few milli-arcsec (mas) a new frame to calibrate ground-based observations has immediately become available, thus disclosing a new possibility of exploitation for archive data. We
