Outgassing induced acceleration of comet 67P/Churyumov-Gerasimenko
Tobias Kramer, Matthias Laeuter
Cometary activity affects the orbital motion and rotation state due to sublimation induced forces. The availability of precise rotation-axis orientation and position data from the…

Comet 67P/Churyumov-Gerasimenko rotation changes derived from sublimation induced torques
Tobias Kramer, Matthias Laeuter, Stubbe Hviid +3
(Context) The change of the rotation period and the orientation of the rotation axis of comet 67P/Churyumov-Gerasimenko (67P/C-G) is deducible from images taken by the scientific i…

Surface localization of gas sources on comet 67P/Churyumov-Gerasimenko based on DFMS/COPS data
Matthias Laeuter, Tobias Kramer, Martin Rubin +1
We reconstruct the temporal evolution of the source distribution for the four major gas species H2O, CO2, CO, and O2 on the surface of comet 67P/Churyumov-Gerasimenko during its 20…
