Constraints on the ejecting-crust activity model on comet 67P/Churyumov-Gerasimenko
Nicholas Attree, Pedro Gutiérrez, Christian Schuckart +6
Reproducing the observed activity of comets with thermophysical models remains a primary challenge of cometary science. We use a pebble-based thermophysical model of gas-pressure b…
Localised ejection of dust and chunks on comet 67P/Churyumov-Gerasimenko: testing how comets work
Nicholas Attree, Christian Schuckart, Dorothea Bischoff +2
We extend an existing thermophysical activity model of comet 67P/Churyumov-Gerasimenko to include pressure buildup inside the pebbles making up the nucleus. We test various quantit…
A quantitative description of comet 67P's dust and gas production remains enigmatic
Dorothea Bischoff, Christian Schuckart, Nicholas Attree +2
The mechanism of dust emission from a cometary nucleus is still an open question and thermophysical models have problems reproducing outgassing and dust productions rates simultane…
Sub-mm/mm optical properties of real protoplanetary matter derived from Rosetta/MIRO observations of comet 67P
Johanna Bürger, Thilo Glißmann, Anthony Lethuillier +6
Optical properties are required for the correct understanding and modelling of protoplanetary and debris discs. By assuming that comets are the most pristine bodies in the solar sy…
A method to distinguish between micro- and macro-granular surfaces of small Solar System bodies
D. Bischoff, B. Gundlach, J. Blum
The surface granularity of small Solar System bodies is diverse through the different types of planetary bodies and even for specific objects it is often not known in detail. One o…
Sticky or not sticky? Measurements of the tensile strength of micro-granular organic materials
Dorothea Bischoff, Christopher Kreuzig, David Haack +2
Knowledge of the mechanical properties of protoplanetary and cometary matter is of key importance to better understand the activity of comets and the early stages of planet formati…
