SUMMARY:Jean Teyssandier (Cornell University\, USA)
DESCRIPTION:Title: Orbital evolution during planet-⁠disc interactions \nAbstract: The origin and wide distribution of eccentricities and inclinations in planetary systems remains to be explained\, in particular in the context of planet-disc interactions. In this talk I will present a study of the evolution of eccentricity in discs and planets that combines methods from celestial mechanics and hydrodynamics\, and takes the form of a linear secular theory. I will compare the predictions of this linear theory against direct hydrodynamical simulations and show how eccentricity can grow. I will discuss what these results imply for the orbital structure of protoplanetary discs and young planetary systems. I will also discuss how moderate inclinations can be generated via similar mechanisms.
