The source of electrons at comet 67P
P. Stephenson, A. Beth, J. Deca +8
We examine the origin of electrons in a weakly outgassing comet, using Rosetta mission data and a 3D collisional model of electrons at a comet. We have calculated a new dataset of…

Solar wind charge exchange in cometary atmospheres III. Results from the Rosetta mission to comet 67P/Churyumov-Gerasimenko
Cyril Simon Wedlund, Etienne Behar, Hans Nilsson +12
Solar wind charge-changing reactions are of paramount importance to the physico-chemistry of the atmosphere of a comet. The ESA/Rosetta mission to comet 67P/Churyumov-Gerasimenko (…

Ion velocity and electron temperature inside and around the diamagnetic cavity of comet 67P
Elias Odelstad, Anders I. Eriksson, Fredrik L. Johansson +7
A major point of interest in cometary plasma physics has been the diamagnetic cavity, an unmagnetized region in the inner-most part of the coma. Here, we combine Langmuir and Mutua…
