A Smoking Gun for Planetesimal Formation: Charge Driven Growth into a New Size Range
Jens Teiser, Maximilian Kruss, Felix Jungmann +1
Collisions electrically charge grains which promotes growth by coagulation. We present aggregation experiments with three large ensembles of basalt beads ($150\,μ\mathrm{m} - 180\,…
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…
Composition and Size Dependent Sorting in Preplanetary Growth: Seeding the Formation of Mercury-like Planets
Maximilian Kruss, Gerhard Wurm
In an earlier work, we found that large metallic iron fractions in dust aggregates and strong magnetic fields boost preplanetary growth. This sets an initial bias for the formation…
Wind erosion on Mars and other small terrestrial planets
Maximilian Kruss, Grzegorz Musiolik, Tunahan Demirci +2
We carried out wind tunnel experiments on parabolic flights with 100 m Mojave Mars simulant sand. The experiments result in shear stress thresholds and erosion rates for varying…
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…
Seeding the Formation of Mercurys: An Iron-sensitive Bouncing Barrier in Disk Magnetic Fields
Maximilian Kruss, Gerhard Wurm
The inner part of protoplanetary disks can be threaded by strong magnetic fields. In laboratory levitation experiments, we study how magnetic fields up to 7 mT influence the aggreg…
