Impact of magneto-rotational instability on grain growth in protoplanetary disks: II. Increased grain collisional velocities

Munan Gong, Alexei V. Ivlev, Vitaly Akimkin +1

Turbulence is the dominant source of collisional velocities for grains with a wide range of sizes in protoplanetary disks. So far, only Kolmogorov turbulence has been considered fo…
