Drifting inwards in protoplanetary discs II: The effect of water on sticking properties at increasing temperatures
C. Pillich, T. Bogdan, J. Landers +2
In previous laboratory experiments, we measured the temperature dependence of sticking forces between micrometer grains of chondritic composition. The data showed a decrease in sur…
Laboratory Impact Splash Experiments to Simulate Asteroid Surfaces
Tabea Bogdan, Jonathan E. Kollmer, Jens Teiser +2
Granular material that is bound by the low gravity of a small asteroid is mobilized by slow velocity impacts. These splashes generated by impacts might play an important role in sc…
Drifting inwards in protoplanetary discs I Sticking of chondritic dust at increasing temperatures
T. Bogdan, C. Pillich, J. Landers +2
Sticking properties rule the early phases of pebble growth in protoplanetary discs in which grains regularly travel from cold, water-rich regions to the warm inner part. This drift…
Planetesimals in Rarefied Gas: Wind Erosion in Slip Flow
Tunahan Demirci, Niclas Schneider, Tobias Steinpilz +3
A planetesimal moves through the gas of its protoplanetary disc where it experiences a head wind. Though the ambient pressure is low, this wind can erode and ultimately destroy the…
Are Pebble Pile Planetesimals Doomed?
Tunahan Demirci, Maximilian Kruss, Jens Teiser +4
In parabolic flight experiments we studied the wind induced erosion of granular beds composed of spherical glass beads at low gravity and low ambient pressure. Varying g-levels wer…
Constraints on Compound Chondrule Formation from Laboratory High-Temperature Collisions
Tabea Bogdan, Jens Teiser, Nikolai Fischer +2
In laboratory experiments, spherical 1 mm-wide glass and basalt particles are heated, and the hot particles collide at about 1m/s with a flat glass target that is at room temperatu…
