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…
Laboratory Impact Splash Experiments to Simulate Asteroid Surfaces
Tabea Bogdan, Jonathan E. Kollmer, Jens Teiser +2
Granular material that is bound by the low gravity of a small asteroid is mobilized by slow velocity impacts. These splashes generated by impacts might play an important role in sc…
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…
Lifting Grains by the Transient Low Pressure in a Martian Dust Devil
Tetyana Bila, Gerhard Wurm, Florence Chioma Onyeagusi +1
Lifting dust and sand into the thin Martian atmosphere is a challenging problem. Atmospheric pressure excursions within dust devils have been proposed to support lifting. We verify…
