Ejected Particles after Impact Splash on Mars: Aggregates and Aerodynamics
Tim Becker, Jens Teiser, Teresa Jardiel +6
Our earlier laboratory measurements showed that low-velocity sand impacts release fine <5 μm dust from a Martian simulant soil. This dust will become airborne in the Martian atmosp…
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…
Understanding planet formation using microgravity experiments
Gerhard Wurm, Jens Teiser
In 2018, images were released of a planet being formed around the star PDS 70, offering a tantalizing glimpse into how planets come into being. However, many questions remain about…
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…
The Curie line in protoplanetary disks and the formation of Mercury-like planets
T. Bogdan, C. Pillich, J. Landers +2
In laboratory experiments, we heated chondritic material up to 1400K in a hydrogen atmosphere. Moessbauer spectroscopy and magnetometry reveal that, at high temperatures, metallic…
Electrostatic Repulsion of Dust from Planetary Surfaces
F. Chioma Onyeagusi, Felix Jungmann, Jens Teiser +1
Surfaces of planetary bodies can have strong electric fields, subjecting conductive grains to repulsive electrostatic forces. This has been proposed as mechanism to eject grains fr…
