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…
