Uncertainty estimation of incoming comet trajectories with a thermophysical non-gravitational force model for Comet Interceptor encounter planning
Nicholas Attree, Pieter de Boer, Pedro Gutiérrez +3
The European Space Agency Comet Interceptor mission is designed to fly-by an as-yet undetermined incoming long-period or dynamically-new comet, which will require an accurate predi…
Towards a coupled activity-fallback model for comets I) 67P/Churyumov-Gerasimenko's water activity from a microphysics model with dynamic dust-depth
Nicholas Attree, Yuri Skorov, Pedro Gutiérrez +4
We apply a two-layer thermophysical model, with water sublimating from below a dust-crust with dynamically varying depth, to simulate the water outgassing rate, dust-ejections, and…
Dense photometry validation of super-fast-rotating asteroid candidates
Bojan Novaković, Pedro J. Gutiérrez
Super-fast rotators (SFRs; P < 2.2 hr) are of great importance in asteroid studies; yet, many reported detections suffer from aliasing caused by an insufficient observation cadence…
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…
Activity of comet 7P/Pons-Winnecke during the 2021 apparition
Irene Mariblanca-Escalona, Luisa M. Lara, Fernando Moreno +2
Comet 7P/Pons-Winnecke was observed from the Calar Alto Observatory (Spain) for four months during the 2021 inbound apparition. Broad-band visible images were taken between 1.71 an…
Varying water activity and momentum transfer on comet 67P/Churyumov-Gerasimenko from its non-gravitational forces and torques
N. Attree, P. Gutiérrez, O. Groussin +9
We investigate the ability of a simultaneous fitting of comet 67P/Churyumov-Gerasimenko's non-gravitational forces, torques and total water-outgassing rate, as observed by Rosetta,…
Modelling the water and carbon dioxide production rates of Comet 67P/Churyumov-Gerasimenko
Björn J. R. Davidsson, Nalin H. Samarasinha, Davide Farnocchia +1
The European Space Agency Rosetta/Philae mission to Comet 67P/Churyumov-Gerasimenko in 2014-2016 is the most complete and diverse investigation of a comet carried out thus far. Yet…
