Simulating secondary electron and ion emission from the Cassini spacecraft in Saturn's ionosphere
Zeqi Zhang, Ravindra T. Desai, Oleg Shebanits +3
The Cassini spacecraft's Grand Finale flybys through Saturn's ionosphere provided unprecedented insight into the composition and dynamics of the gas giant's upper atmosphere and a…
Implications from secondary emission from neutral impact on Cassini plasma and dust measurements
Fredrik Leffe Johansson, Erik Vigren, Jack Hunter Waite +4
We investigate the role of secondary electron and ion emission from impact of gas molecules on the Cassini Langmuir Probe (RPWS-LP, or LP) measurements in the ionosphere of Saturn.…
Plasma densities, flow and Solar EUV flux at comet 67P - A cross-calibration approach
F. L. Johansson, A. I. Eriksson, E. Vigren +7
During its two-year mission at comet 67P, Rosetta nearly continuously monitored the inner coma plasma environment for gas production rates varying over three orders of magnitude, a…
A charging model for the Rosetta spacecraft
F. L. Johansson, A. I. Eriksson, N. Gilet +5
Context. The electrostatic potential of a spacecraft, VS, is important for the capabilities of in situ plasma measurements. Rosetta has been found to be negatively charged during m…
Solar flares observed by Rosetta at comet 67P
N. J. T. Edberg, F. L. Johansson, A. I. Eriksson +6
Context. The Rosetta spacecraft made continuous measurements of the coma of comet 67P/ Churyumov-Gerasimenko (67P) for more than two years. The plasma in the coma appeared very dyn…
Solar wind interaction with comet 67P: impacts of corotating interaction regions
Niklas J. T. Edberg, A. I. Eriksson, E. Odelstad +18
We present observations from the Rosetta Plasma Consortium of the effects of stormy solar wind on comet 67P/Churyumov-Gerasimenko. Four corotating interaction regions (CIRs), where…
CME impact on comet 67P/Churyumov-Gerasimenko
Niklas J. T. Edberg, M. Alho, M. André +22
We present Rosetta observations from comet 67P/Churyumov-Gerasimenko during the impact of a coronal mass ejection (CME). The CME impacted on 5-6 Oct 2015, when Rosetta was about 80…
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…
Measurements of the electrostatic potential of Rosetta at comet 67P
Elias Odelstad, Gabriella Stenberg-Wieser, Martin Wieser +3
We present and compare measurements of the spacecraft potential (Vs/c) of the Rosetta space- craft throughout its stay in the inner coma of comet 67P/Churyumov-Gerasimenko, by the…
Cold and warm electrons at comet 67P
A. I. Eriksson, I. A. D. Engelhardt, M. Andre +20
Strong electron cooling on the neutral gas in cometary comae has been predicted for a long time, but actual measurements of low electron temperature are scarce. We present in situ…
