The motion of chondrules and other particles in a protoplanetary disc with temperature fluctuations
Christoph Loesche, Gerhard Wurm, Thorben Kelling +2
We consider the mechanism of photophoretic transport in protoplanetary disks that are optically thick to radiation. Here, photophoresis is not caused by the central star but by tem…
Self-Sustained Recycling in the Inner Dust Ring of Pre-Transitional Disks
Tim Husmann, Christoph Loesche, Gerhard Wurm
Observations of pre-transitional disks show a narrow inner dust ring and a larger outer one. They are separated by a cavity with no or only little dust. We propose an efficient rec…
Photophoresis on particles hotter/colder than the ambient gas for the entire range of pressures
Christoph Loesche, Tim Husmann
Small, illuminated aerosol particles embedded in a gas experience a photophoretic force. Most approximations assume the mean particle surface temperature to be effectively the gas…
Photophoresis on particles hotter/colder than the ambient gas in the free molecular flow
C. Loesche, G. Wurm, T. Jankowski +1
Aerosol particles experience significant photophoretic forces at low pressure. Previous work assumed the average particle temperature to be very close to the gas temperature. This…
Photophoretic Strength on Chondrules. 2. Experiment
Christoph Loesche, Jens Teiser, Gerhard Wurm +3
Photophoretic motion can transport illuminated particles in protoplanetary disks. In a previous paper we focused on the modeling of steady state photophoretic forces based on the c…
Photophoretic Strength on Chondrules 1: Modeling
Christoph Loesche, Gerhard Wurm, Jens Teiser +2
Photophoresis is a physical process that transports particles in optical thin parts of protoplanetary disks, especially at the inner edge and at the optically surface. To model the…
Thermal and Photophoretic Properties of Dust Mantled Chondrules and Sorting in the Solar Nebula
Christoph Loesche, Gerhard Wurm
Many chondrules are found to be surrounded by a fine grained rim. Supposedly, these rims were acquired from dust accreted to the chondrules in a protoplanetary disk. In numerical s…
