Destruction of eccentric planetesimals by ram pressure and erosion
Tunahan Demirci, Niclas Schneider, Jens Teiser +1
Small, pebble-sized objects and large bodies of planetesimal size both play important roles in planet formation. They form the evolutionary steps of dust growth in their own respec…
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…
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…
Dense Particle Clouds in Laboratory Experiments in Context of Drafting and Streaming Instability
Niclas Schneider, Gerhard Wurm, Jens Teiser +2
The streaming instability, as an example of instabilities driven by particle feedback on a gas flow, has been proven to have a major role in controlling the formation of planetesim…
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…
