AST Colloquium - Unveiling the Architecture of Young Extrasolar Systems
Unveiling the Architecture of Young Extrasolar SystemsDr. Laetitia RodetCornell UniversityAbstract:Our knowledge about extrasolar systems has dramatically increased for the last two decades. Statistics and case studies reveal the mechanisms of planetary formation and evolution, that shed light on the history of our own Solar System. But though new planets are discovered on a daily basis, our understanding of the architecture of planetary systems is still sparse, because a large part of the planetary population remains below the detection thresholds. She will here talk about the recent and future insights provided by the direct imaging method (looking directly for the light of exoplanets, in opposition to the indirect detection methods). This method unveils the outer architecture of young systems, where the dynamical interactions are frequent. She will, in particular, introduce you to some of the most puzzling systems that challenge our current understanding, the tools we use to study them and what we could hope to learn from their peculiarities.Speaker Bio:Laetitia Rodet is currently a research associate at Cornell University, Ithaca NY. She is working in Prof. Lai's theoretical astrophysics group, on the dynamics of planetary systems. Previously, she got her Ph.D. from Université Grenoble-Alpes in France, where she studied the dynamics of young imaged systems. There, she worked in close collaborations with observers, to further constrain and understand the architecture of extrasolar systems. She is part of the SPHERE consortium, which aims at directly imaging giant planets and disks with the SPHERE instrument, installed on the VLT in Chile.Intended Audience:No background knowledge is required. All are welcome.
