Early Planet Formation from an Experimentalist’s Point of View

Planet formation starts in gaseous protoplanetary disks. Small grains move around, collide, stick together and grow. However, many collisional roads also lead to destruction of larger bodies. Which ones are prevailing and if this is the basic way to planet formation is still an open question, but there are modes to grow particles to larger size even in ‘high speed’ collisions. This talk will also touch upon processes of transport, growth and destruction off the beaten track, which are induced by stellar light and thermal radiation of the disk adding some unexpected aspects, which might make at least some problems easier (or others more complex).
