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…
Free Collisions in a Microgravity Many-Particle Experiment. II. The Collision Dynamics of Dust-Coated Chondrules
Eike Beitz, Carsten Güttler, René Weidling +1
The formation of planetesimals in the early Solar System is hardly understood, and in particular the growth of dust aggregates above millimeter sizes has recently turned out to be…
The Physics of Protoplanetesimal Dust Agglomerates. Vi. Erosion of Large Aggregates as a Source of Micrometer-Sized Particles
Rainer Schräpler, Jürgen Blum
Observed protoplanetary disks consist of a large amount of micrometer-sized particles. Dullemond and Dominik (2005) pointed out for the first time the difficulty in explaining the…
Outgassing of icy bodies in the solar system - I. The sublimation of hexagonal water ice through dust layers
Bastian Gundlach, Yuri Skorov, Jürgen Blum
Our knowledge about the physical processes determining the activity of comets were mainly influenced by several extremely successful space missions, the predictions of theoretical…
Low-velocity collisions of centimeter-sized dust aggregates
Eike Beitz, Carsten Güttler, Jürgen Blum +3
Collisions between centimeter- to decimeter-sized dusty bodies are important to understand the mechanisms leading to the formation of planetesimals. We thus performed laboratory ex…
Micrometer-sized ice particles for planetary-science experiments - I. Preparation, critical rolling friction force, and specific surface energy
Bastian Gundlach, Stephan Kilias, Eike Beitz +1
Coagulation models assume a higher sticking threshold for micrometer-sized ice particles than for micrometer-sized silicate particles. However, in contrast to silicates, laboratory…
