Abstract

Protoplanetary disks are the birthplace of planets. They are formed as a consequence of angular momentum conservation during the gravitational collapse of dense cores. These disks are, most of the time, not formed in isolation but rather within a population, as they are usually born in highly turbulent and massive molecular clouds. Investigating the disk population formation as a self-consistent process is crucial to statistically examine the initial conditions of protoplanetary disks. Those initial conditions, probably inherited from the large-scale properties (magnetic field, turbulence, density, etc…), can only be obtained from a full modelling of the molecular clouds.

In this presentation, he will show recent RAMSES (Teyssier, 2002) calculations of disk population formation from massive protostellar clumps (similar to Lebreuilly et al., 2021). With the help of these models, he will demonstrate the importance of the large-scale conditions on the properties of the disk populations. He will also present new results that include dust (dynamics and growth) for the first time in this approach.

 

About the Speaker

Ugo LiberallyUgo Lebreuilly is an expert in star formation and in the evolution of interstellar dust.

He defended his Ph.D thesis "Star formation: A dynamical study of interstellar dust" at École Normale Supérieure de Lyon in 2020 and is, since then, a post-doctoral researcher at CEA Saclay taking part in the ERC SYNERGY ECOGAL (PIs: Pr. Hennebelle, Pr. Klessen, Pr. Molinari and Pr. Testi) that aims for a unified model of the gas in the milky way from the galactic scales down to those of the protoplanetary disks.
