Charged Clouds of Ionized Gas Emerge from Tribocharging Grains
Patrick Hock, Jens Teiser, Gerhard Wurm
If two solid particles collide, charge is exchanged. However, this transfer is not restricted to the surface of the particle. Ions are also dispersed into the environment. They for…
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…
Gas Phase Ions in Protoplanetary Disks from Collisions of Solids
Jakob Penner, Gerhard Wurm, Jens Teiser
Ionization is important for magnetohydrodynamics and chemistry in protoplanetary disks but known ionization sources are often weak along the midplane. We present, for the first tim…
