Forbidden planetesimals
Laurent Schönau, Jens Teiser, Tunahan Demirci +5
Planetesimals are born fragile and are subject to destruction by wind erosion as they move through the gas of a protoplanetary disk. In microgravity experiments, we determined the…
Thermal Creep on Mars: Visualizing a Soil Layer under Tension
Tetyana Bila, Jonathan Kollmer, Jens Teiser +1
At low ambient pressure, temperature gradients in porous soil lead to a gas flow, called thermal creep. With this regard, Mars is a unique as the conditions for thermal creep to oc…
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…
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…
