Dense photometry validation of super-fast-rotating asteroid candidates
Bojan NovakoviÄ, 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,…
