Observation of aerodynamic instability in the flow of a particle stream in a dilute gas
Holly L. Capelo, Jan Molacek, Michiel Lambrechts +5
Forming macroscopic solid bodies in circumstellar discs requires local dust concentration levels significantly higher than the mean. Interactions of the dust particles with the gas…
Experiments on cometary activity: ejection of dust aggregates from a sublimating water-ice surface
D. Bischoff, B. Gundlach, M. Neuhaus +1
The gas-driven dust activity of comets is still an unresolved question in cometary science. In the past, it was believed that comets are dirty snowballs and that the dust is ejecte…
Impact-induced energy transfer and dissipation in granular clusters under microgravity conditions
Hiroaki Katsuragi, Jürgen Blum
The impact-induced energy transfer and dissipation in granular targets without any confining walls are studied by microgravity experiments. A solid projectile impacts into a granul…
The optical characteristics of the dust of sungrazing comet C/2012 S1 (ISON) observed at large heliocentric distances
Oleksandra Ivanova, Volodymyr Reshetnyk, Yury Skorov +7
We present an analysis of the photometric and spectroscopic data of the comet C/2012 S1 (ISON) observed at the heliocentric distances of 6.21÷4.81 AU. The photometric observations…
Asteroid Ryugu Before the Hayabusa2 Encounter
Koji Wada, Matthias Grott, Patrick Michel +31
Asteroid (162173) Ryugu is the target object of Hayabusa2, an asteroid exploration and sample return mission led by Japan Aerospace Exploration Agency (JAXA). Ground-based observat…
Dust evolution in protoplanetary discs and the formation of planetesimals. What have we learned from laboratory experiments?
Jürgen Blum
After 25 years of laboratory research on protoplanetary dust agglomeration, a consistent picture of the various processes that involve colliding dust aggregates has emerged. Beside…
