Séminaire “Isotopic constraints on the structure of the protoplanetary disk and the origin of planets in the solar system” par Yves Marrochi (CRPG)

The detection of exoplanets and accretion disks around newborn stars has spawned new models of how our Solar System formed and evolved. Meteorites as probes of the early times can provide important constraints to these models. Stable isotope anomalies in meteorites have recently emerged as key tracers of material flow in the early Solar System, allowing a “planetary isotopic genealogy”.to be established. In this talk, I will show how the recent data and modelling have improved our understanding of the structure of the earl Solar System and the origin of planets.
