Collisional Charging in the Low Pressure Range of Protoplanetary Disks
T. Becker, T. Steinpilz, J. Teiser +1
In recent years, collisional charging has been proposed to promote the growth of pebbles in early phases of planet formation. Ambient pressure in protoplanetary disks spans a wide…
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…
Sticking Properties of Silicates in Planetesimal Formation Revisited
Tobias Steinpilz, Jens Teiser, Gerhard Wurm
In the past, laboratory experiments and theoretical calculations showed a mismatch in derived sticking properties of silicates in the context of planetesimal formation. It has been…
A challenge for Martian lightning: Limits of collisional charging at low pressure
Gerhard Wurm, Lars Schmidt, Tobias Steinpilz +2
Collisional charging is one potential initial step in generating lightning. In this work, we study the charging of colliding monodisperse, spherical basalt grains depending on ambi…
Is There a Temperature Limit in Planet Formation at 1000 K?
Tunahan Demirci, Jens Teiser, Tobias Steinpilz +4
Dust drifting inward in protoplanetary disks is subject to increasing temperatures. In laboratory experiments, we tempered basaltic dust between 873 K and 1273 K and find that the…
