Submillimetre-sized dust aggregate collision and growth properties
J. Brisset, D. Heißelmann, S. Kothe +2
The collisional and sticking properties of sub-mm-sized aggregates composed of protoplanetary dust analogue material are measured, including the statistical threshold velocity betw…
Collisions of small ice particles under microgravity conditions (II): Does the chemical composition of the ice change the collisional properties?
C. R. Hill, D. Heißelmann, J. Blum +1
Context: Understanding the collisional properties of ice is important for understanding both the early stages of planet formation and the evolution of planetary ring systems. Simpl…
Collisions of small ice particles under microgravity conditions
C. R. Hill, D. Heißelmann, J. Blum +1
Planetisimals are thought to be formed from the solid material of a protoplanetary disk by a process of dust aggregation. It is not known how growth proceeds to kilometre sizes, bu…
Experimental Studies on the Aggregation Properties of Ice and Dust in Planet-Forming Regions
Daniel Heißelmann, Helen J. Fraser, Jürgen Blum
To reveal the formation of planetesimals it is of great importance to understand the collision behavior of the dusty and icy aggregates they have formed from. We present an experim…
Microgravity experiments on the collisional behavior of Saturnian ring particles
Daniel Heißelmann, Jürgen Blum, Helen J. Fraser +1
In this paper we present results of two novel experimental methods to investigate the collisional behavior of individual macroscopic icy bodies. The experiments reported here were…
The Flow Of Granular Matter Under Reduced-Gravity Conditions
Paul G. Hofmeister, Jürgen Blum, Daniel Heißelmann
To gain a better understanding of the surfaces of planets and small bodies in the solar system, the flow behavior of granular material for various gravity levels is of utmost inter…
