Observation of bottom-up formation for charged grain aggregates related to pre-planetary evolution beyond the bouncing barrier
Felix Jungmann, Gerhard Wurm
Context. Particles in protoplanetary disks go through a number of phases that are dominated by collisions. In each of these events, grains exchange electrical charge via triboelect…
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…
A Smoking Gun for Planetesimal Formation: Charge Driven Growth into a New Size Range
Jens Teiser, Maximilian Kruss, Felix Jungmann +1
Collisions electrically charge grains which promotes growth by coagulation. We present aggregation experiments with three large ensembles of basalt beads ($150\,μ\mathrm{m} - 180\,…
Cosmic radiation does not prevent collisional charging in (Pre)-Planetary Atmospheres
Felix Jungmann, Tetyana Bila, Laura Kleinert +8
In (pre)-planetary environments, dust and sand grains regularly collide. They electrically charge and discharge during these events. In this work, we study if cosmic radiation has…
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…
Are Pebble Pile Planetesimals Doomed?
Tunahan Demirci, Maximilian Kruss, Jens Teiser +4
In parabolic flight experiments we studied the wind induced erosion of granular beds composed of spherical glass beads at low gravity and low ambient pressure. Varying g-levels wer…
