New constraints on the chemical composition and outgassing of 67P/Churyumov-Gerasimenko

Thomas, N.; Rubin, M.; Mousis, O. +4 more

Strong heterogeneities in the composition of the volatile species have been detected in the coma of comet 67P/Churyumov-Gerasimenko (67P/C-G) by the ROSINA instrument onboard the ESA's Rosetta spacecraft. However, it is not clear if these heterogeneities are indicative of heterogeneities in the near-surface nucleus composition or if the coma compo…

Dynamics of material ejected from the Hatmehit depression and landslides on comet 67P/Churyumov-Gerasimenko

Czechowski, Leszek; Kossacki, Konrad J.

In this work we investigate trajectories and regions of deposition of material ejected from depression Hatmehit on comet 67P/Churyumov-Gerasimenko. This depression, located on the lobe Head, could be a result of endogenic, possibly still ongoing, activity. We calculated trajectories of the ejecta with different initial velocities and we determined…
