The dawn of planets

By combining detailed knowledge of the Solar System with a statistical approach to protoplanetary disks and exoplanet populations, we aim to constrain a global scenario for planet formation. The Dawn of Planets project seeks to test the hypothesis of early planetary formation, occurring in the first phases of disk evolution, and to assess its compatibility with constraints derived from Solar System meteorites. To do this, we will statistically study the initial conditions and environment of disks, their influence on disk evolution (turbulence, substructures, dissipation), and the associated planetary formation pathways, notably via flow instability. Finally, we will link the evolution of gas and dust in the disk to the properties of meteorites formed in the Solar System. By combining theoretical modeling with advanced numerical simulations, the project contributes to axis Q1, related to the formation of large cosmological structures, while providing key insights for axis Q2 on understanding active astrophysical sources and their environments. The recruitment of a PhD student ensures these studies are embedded in a long-term perspective, essential for the accumulation and interpretation of multi-messenger signals.

The project’s principal investigator is Ugo Lebreuilly (AIM).
