Ice Particles Trapped by Temperature Gradients at mbar Pressure
Thorben Kelling, Gerhard Wurm, Christoph Dürmann
In laboratory experiments we observe that ice particles (\leq100 μm) entrained in a low pressure atmosphere (~1 mbar) get trapped by temperature gradients between three reservoirs…
A Mechanism to Produce the Small Dust Observed in Protoplanetary Disks
Thorben Kelling, Gerhard Wurm
Small (sub)-micron dust is present over the entire lifetime of protoplanetary disks. As aggregation readily depletes small particles, one explanation might be that dust is continuo…
Self-sustained Levitation of Dust Aggregate Ensembles by Temperature Gradient Induced Overpressures
Thorben Kelling, Gerhard Wurm
In laboratory experiments we observe dust aggregates from 100 μm to 1 cm in size composed of micrometer sized grains levitating over a hot surface. Depending on the dust sample agg…
Dust Ejection from Planetary Bodies by Temperature Gradients: Laboratory Experiments
Thorben Kelling, Gerhard Wurm, Miroslav Kocifaj +2
Laboratory experiments show that dusty bodies in a gaseous environment eject dust particles if they are illuminated. We find that even more intense dust eruptions occur when the li…
