Description du projet
Des méthodes statistiques avancées pour stimuler l’exploration de l’évolution des exoplanètes
Financé par le programme Actions Marie Skłodowska-Curie, le projet SPICES se propose de développer des méthodes statistiques avancées permettant d’imager les exoplanètes et caractériser les disques de planètes en formation. Plus de 5 000 exoplanètes ayant déjà été détectées, la compréhension de leur architecture est cruciale. SPICES se concentrera sur les planètes géantes à longue période de révolution telles que Jupiter, qui influencent l’évolution des systèmes planétaires et déposent des signatures dans les disques protoplanétaires. En se dissipant au fil du temps, ces disques protoplanétaires riches en gaz forment des planètes telluriques et des populations de poussières de deuxième génération. L’observation de ces étapes est essentielle pour comprendre la formation et l’évolution des planètes. SPICES comblera le fossé entre les méthodes d’analyse des données et les données de haute qualité, et fournira de nouvelles informations concernant la formation et l’évolution des systèmes planétaires.
Objectif
The SPICES project applies and develops state-of-the-art statistical methods to image forming exoplanets and characterize planet-forming disks. More than 5000 exoplanets have been detected as of today, showing a great diversity in planetary system architectures that is still not entirely understood. Many of these planets were found in systems that have dissipated their birth environment, and do not allow for the study of the early times of planet formation. Originally formed in gaseous protoplanetary disks surrounding newborn stars, long-period giant planets such as Jupiter shape the evolution of planetary systems including that in our own Solar System. They can gravitationally interact with disks and imprint signatures such as gaps, rings, and spiral arms. Such features are routinely observed in high resolution disk observations, suggesting that a large population of massive planets are actively sculpting protoplanetary disks. Later on, these gas-rich disks dissipate within a few Myr while terrestrial planets form, and planetesimal collisions lead to second- generation dust populations (i.e. debris disks). Observation of planetary systems in different stages is therefore key to understanding their formation and evolution. Using modern statistics-based methods, I propose the Statistics-driven Planet Imaging in Circumstellar EnvironmentS (SPICES) project to perform unprecedented inspection of planet forming disks, thus detecting planets that are embedded in disks while characterizing disk mineralogy. By doing so, I will bridge the gap between revolutionary data analysis methods in analyzing and the myriad of high-quality data, and ultimately provide new insights into the formation and evolution of planetary systems.
