Dust evolution from star forming environments to protoplanetary disks
Abstract :
Dust is a key component of the ISM. It plays a major role in radiative transfer processes, the interplay between the neutral gas and the magnetic fields, the chemistry and, of course, planet formation. In the ISM, dust dynamics can significantly differ from the gas leading to variations of dust concentration. In addition, dust grains can stick or fragment through collisions which also alters their size distribution. In this talk, I will first present our state-of-the-art methods to tackle gas and dust dynamics and our recent efforts to model dust-dust sticking and fragmentation. Then, I will present simulations of dust evolution in various environments such as molecular clouds, collapsing dense cores and newly born protoplanetary disks
