Clusters of tribocharged dust aggregates as pebbles in protoplanetary disks
F. C. Onyeagusi, J. Teiser, G. Wurm
In recent years, the tribocharging of colliding and bouncing submillimeter (submm) particles has been studied as a possible mechanism promoting the formation of large pebbles on ce…
The growth of super-large pre-planetary pebbles to an impact erosion limit
J. Teiser, J. Penner, K. Joeris +4
Early dust evolution in protoplanetary disks is dominated by sticking collisions. However, this initial phase of particle growth faces constraints - notably from destructive encoun…
Ejected Particles after Impact Splash on Mars: Electrification
T. Becker, F. C. Onyeagusi, J. Teiser +7
Within the RoadMap project we investigated the microphysical aspects of particle collisions during saltation on the Martian surface in laboratory experiments. Following the size di…
The Dissolution of Planetesimals in Electrostatic Fields
F. Chioma Onyeagusi, Jens Teiser, Tim Becker +1
Planetesimals or smaller bodies in protoplanetary disks are often considered to form as pebble piles in current planet formation models. They are supposed to be large but loose, we…
