| I will talk about the dynamics and growth of dust particles in initially gravitationally unstable protoplanetary disks during the initial 1 Myr of disk evolution. I will show that the level of turbulence in the disk strongly affects the dust evolution. I will present that a strong correlation exists between the gas and pebble fluxes in the disk and that radial surface density distribution of pebbles in the disk shows power-law distribution with an index similar to that of the Minimum-mass solar nebula (MMSN) regardless of the disk mass. I will demonstrate that the centimeter-sized pebbles forming in the outer parts of low turbulence disks migrate inwards and pile up in the inner disk forming a ring structure. The ring structure could possibly lead to the formation of planetesimals by the streaming instability and the early growth of embryos by pebble accretion. |
