Erosion of dust aggregates
Alexander Seizinger, Sebastiaan Krijt, Wilhelm Kley
Aims: The aim of this work is to gain a deeper insight into how much different aggregate types are affected by erosion. Especially, it is important to study the influence of the ve…
Tensile & shear strength of porous dust agglomerates
Alexander Seizinger, Roland Speith, Wilhelm Kley
Context.Within the sequential accretion scenario of planet formation, planets are build up through a sequence sticking collisions. The outcome of collisions between porous dust agg…
Bouncing Behavior of Microscopic Dust Aggregates
Alexander Seizinger, Wilhelm Kley
Context: Bouncing collisions of dust aggregates within the protoplanetary may have a significant impact on the growth process of planetesimals. Yet, the conditions that result in b…
The physics of protoplanetesimal dust agglomerates. VII The low-velocity collision behavior of large dust agglomerates
Rainer Schräpler, Jürgen Blum, Alexander Seizinger +1
We performed micro-gravity collision experiments in our laboratory drop-tower using 5-cm-sized dust agglomerates with volume filling factors of 0.3 and 0.4, respectively. This work…
Compression Behaviour of Porous Dust Agglomerates
Alexander Seizinger, Roland Speith, Wilhelm Kley
The early planetesimal growth proceeds through a sequence of sticking collisions of dust agglomerates. Very uncertain is still the relative velocity regime in which growth rather t…
