The physics of protoplanetesimal dust agglomerates. X. High-velocity collisions between small and large dust agglomerates as growth barrier

Rainer Schräpler, Jürgen Blum, Sebastiaan Krijt +1

In a protoplanetary disk, dust aggregates in the $\mu$m to mm size range possess mean collision velocities of 10 to 60 ms${}^{-1}$ with respect to dm- to m-size bodies. We performed la…
