StreamingInstabilityPlanetesimal Formation

I am exploring how solid particles (roughly mm to cm in size) in planet forming disks clump together and collapse to planetesimal scales.

A very promising mechanism for this clumping is known as the streaming instability. Through state-of-the-art numerical simulations that couple particle gas drag physics to particle self-gravity, I am investigating issues related to planetesimal formation efficiency and the predicted size distribution of planetesimals.
