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…
Development of a cometosheath at comet 67P/Churuyumov-Gerasimenko: A case study comparison of Rosetta observations
H. N. Williamson, H. Nilsson, G. Stenberg Wieser +2
Context: The ionosphere of a comet is known to deflect the solar wind through mass loading, but the interaction is dependent on cometary activity. We investigate the details of thi…
Momentum and pressure balance of a comet ionosphere
Hayley Williamson, Hans Nilsson, Gabriella Stenberg Wieser +3
We calculate the momentum flux and pressure of ions measured by the Ion Composition Analyzer (ICA) on the Rosetta mission at comet 67P/Churyumov-Gerasimenko. The total momentum flu…
The birth and growth of a solar wind cavity around a comet -- Rosetta observations
E. Behar, H. Nilsson, M. Alho +2
The Rosetta mission provided detailed observations of the growth of a cavity in the solar wind around comet 67P/CG. As the comet approached the Sun, the plasma of cometary origin g…
The root of a comet tail - Rosetta ion observations at comet 67P/Churyumov--Gerasimenko
E. Behar, H. Nilsson, P. Henri +7
The first 1000 km of the ion tail of comet 67P/Churyumov-Gerasimenko were explored by the European Rosetta spacecraft, 2.7 au away from the Sun. We characterised the dynamics of bo…
