Periodic Reporting for period 3 - PROTOPLANETS (Establishing a global observational view of the early stages of planet formation and evolution)

Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

Recent observing campaigns have revealed a great diversity in exoplanetary systems whose origin is yet to be understood. It is still unclear how and when planets form, and how they evolve and interact with their host protoplanetary disks while the latter naturally evolve. This project aims to tackle these fundamental questions, with a particular focus on detecting and characterizing forming giant planets, as well as understanding the conditions necessary for terrestrial planet formation.

It is a fundamental problem for our society, as it lies at the heart of the question of the origin of life – replaced in the context of our own solar system, the formation and evolution of giant planets like Jupiter at early stages have a direct impact on the subsequent formation of terrestrial planets and the onset of life.

The main objective of PROTOPLANETS is to establish a global observational picture of the early stages of planetary systems formation and evolution. By searching for protoplanets and studying their imprint on their birth environments, we can constrain the processes happening while planets form.

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

In the first half of the project, our team designed various projects aiming to:
- Search for protoplanets embedded in disks as observed in direct imaging and through their impact on the disk kinematics
- Characterize protoplanets properties through the modelling of kinematical deviations with a semi-analytical approach
- Understand the physico-chemical conditions in disks shaped by giant planets
- Study the gas dynamics in the immediate vicinity of a planet and its chemical evolution
- Understand the evolution of dust grains in protoplanetary disks shaped by planets
- Understand the influence of the extended birth environment on planet formation

Fortschritte, die über den aktuellen Stand der Technik hinausgehen und voraussichtliche potenzielle Auswirkungen (einschließlich der bis dato erzielten sozioökonomischen Auswirkungen und weiter gefassten gesellschaftlichen Auswirkungen des Projekts)

The development of observational and theoretical frameworks for the analysis of disk properties based on gas and dust emission have the potential to bring significant constraints on the nature of protoplanets and the properties of the overall population of giant planets in disks. New data, at high spectral and spatial resolution will allow to probe both inner and outer disk regions, a key approach to assess the diversity of imprints left by those giant planets.
