10/jul/20 – LSST, Gaia, and Perspectives for Stellar Occultations (Dr. Julio Camargo, Observatório Nacional )

Distant small bodies in the Solar System are relatively unaltered fossils of its formation. Therefore, they provide invaluable pieces of information that help us to understand the history and evolution of our planetary system. Stellar occultation is a technique that allows the determination of their sizes and shapes with kilometric accuracy, a detailed investigation of their immediate vicinities, as well as the detection of tenuous atmospheres. The accurate prediction of such events is crucial and will experience a promising new era with Gaia and the Legacy Survey of Space and Time (LSST). In this talk, I’ll briefly discuss the dramatic impact that the astrometry from the Gaia space mission and from deep sky surveys – the LSST in particular – will have on the prediction of stellar occultations and how they may influence the future of the study of small solar system bodies through that technique.
