Are ice particles in the laboratory "good" analogues for collision studies of planet-formation processes?

Abstract: With the discovery of almost 3000 exo-planets it is clear that planet formation is a by-product of star formation, yet in the micron – cm size range, where relative velocities are just a few cm s-1, we still do not know how particles ‘stick’ forming larger ‘boulders’ until gravitational interactions lead to planet formation. It is postulated that icy grains are the key to this process, but this can only be determined empirically, and much uncertainty remains as to whether the icy particles used in collision experiments really resemble those in planet-forming regions. Here we exploit NIMROD’s fast acquisition times and wide Q-range to concurrently characterise the particle size, shape, and ice-phase distributions of a range of icy particle samples prepared by different methods, to feed back to our understanding in planet forming models.
