Experimental study of clusters in dense granular gas and implications for the particle stopping time in protoplanetary disks
Niclas Schneider, Grzegorz Musiolik, Jonathan E. Kollmer +6
In protoplanetary disks, zones of dense particle configuration promote planet formation. Solid particles in dense clouds alter their motion through collective effects and back reac…
Planetesimals in Rarefied Gas: Wind Erosion in Slip Flow
Tunahan Demirci, Niclas Schneider, Tobias Steinpilz +3
A planetesimal moves through the gas of its protoplanetary disc where it experiences a head wind. Though the ambient pressure is low, this wind can erode and ultimately destroy the…
ARISE: A granular matter experiment on the International Space Station
Tobias Steinpilz, Grzegorz Musiolik, Maximilian Kruss +8
We developed an experiment to study different aspects of granular matter under microgravity. The 1.5U small experiment was carried out on the International Space Station. About 350…
Sticking Properties of Silicates in Planetesimal Formation Revisited
Tobias Steinpilz, Jens Teiser, Gerhard Wurm
In the past, laboratory experiments and theoretical calculations showed a mismatch in derived sticking properties of silicates in the context of planetesimal formation. It has been…
A challenge for Martian lightning: Limits of collisional charging at low pressure
Gerhard Wurm, Lars Schmidt, Tobias Steinpilz +2
Collisional charging is one potential initial step in generating lightning. In this work, we study the charging of colliding monodisperse, spherical basalt grains depending on ambi…
Is There a Temperature Limit in Planet Formation at 1000 K?
Tunahan Demirci, Jens Teiser, Tobias Steinpilz +4
Dust drifting inward in protoplanetary disks is subject to increasing temperatures. In laboratory experiments, we tempered basaltic dust between 873 K and 1273 K and find that the…
