Cosmic Dust Aggregation with Stochastic Charging
(Astrophysical Journal, 2013-10-04)
The coagulation of cosmic dust grains is a fundamental process which takes place in astrophysical environments, such as presolar nebulae and circumstellar and protoplanetary disks. Cosmic dust grains can become charged ...
Mode couplings and resonance instabilities in dust clusters
(Physical Review E, 2013-10-16)
The normal modes for three to seven particle two-dimensional (2D) dust clusters in a complex plasma are investigated using an N-body simulation. The ion wakefield downstream of each particle is shown to induce coupling ...
Photophoresis on polydisperse basalt microparticles under microgravity
(Journal of Aerosol Science, 2014-10)
Photophoresis is a force which can dominate the motion of illuminated aerosols in low pressure environments of laboratory experiments, planetary atmospheres or protoplanetary disks. In drop tower experiments we quantified ...
Dust as probe for horizontal field distribution in low pressure gas discharges
(Plasma Sources Science and Technology, 2014-06-23)
Using dust grains as probes in gas discharge plasma is a very promising, but at the same time very challenging method, as the individual external control of dust grains has to be solved. We propose and demonstrate the ...
Interaction force in a vertical dust chain inside a glass box
(Physical Review E, 2014-07-31)
Small number dust particle clusters can be used as probes for plasma diagnostics. The number of dust particles as well as cluster size and shape can be easily controlled employing a glass box placed within a Gaseous ...
