Impact of solar wind turbulence on a planetary bow shock
E. Behar, F. Pucci, C. Simon Wedlund +4
Over the past decades, near-Earth spacecraft observations have provided insights into the physics of the bow shock, suggesting that solar wind intrinsic turbulence influences the b…
Cometary Ionospheres: An Updated Tutorial
Arnaud Beth, Marina Galand, Cyril Simon Wedlund +1
This chapter aims at providing the tools and knowledge to understand and model the plasma environment surrounding comets in the innermost part near the nucleus. In particular, our…
A fast bow shock location predictor-estimator from 2D and 3D analytical models: Application to Mars and the MAVEN mission
C. Simon Wedlund, M. Volwerk, A. Beth +5
We present fast algorithms to automatically estimate the statistical position of the bow shock from spacecraft data, using existing analytical two-dimensional (2D) and three-dimens…
Cometary Plasma Science -- A White Paper in response to the Voyage 2050 Call by the European Space Agency
Charlotte Götz, Herber Gunell, Martin Volwerk +27
Comets hold the key to the understanding of our solar system, its formation and its evolution, and to the fundamental plasma processes at work both in it and beyond it. A comet nuc…
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 charge exchange in cometary atmospheres. I. Charge-changing and ionization cross sections for He and H particles in HO
Cyril Simon Wedlund, Dennis Bodewits, Markku Alho +7
Solar wind charge-changing reactions are of paramount importance to the physico-chemistry of the atmosphere of a comet, mass-loading the solar wind through an effective conversion…
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 (…
Solar wind charge exchange in cometary atmospheres. II. Analytical model
Cyril Simon Wedlund, E. Behar, E. Kallio +7
Solar wind charge-changing reactions are of paramount importance to the physico-chemistry of the atmosphere of a comet because they mass-load the solar wind through an effective co…
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…
Ultraviolet Observations of Coronal Mass Ejection Impact on Comet 67P/Churyumov-Gerasimenko by Rosetta Alice
John W. Noonan, S. Alan Stern, Paul D. Feldman +13
The Alice ultraviolet spectrograph on the European Space Agency Rosetta spacecraft observed comet 67P/Churyumov-Gerasimenko in its orbit around the Sun for just over two years. Ali…
Rosetta photoelectron emission and solar ultraviolet flux at comet 67P
Fredrik L. Johansson, E. Odelstad, J. J. P. Paulsson +10
The Langmuir Probe instrument on Rosetta monitored the photoelectron emission cur- rent of the probes during the Rosetta mission at comet 67P/Churyumov-Gerasimenko, in essence acti…
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…
The Planeterrella experiment: from individual initiative to networking
Jean Lilensten, Gabrielle Provan, Sandrine Grimald +6
Space weather is a relatively new discipline which is generally unknown to the wider public, despite its increasing importance to all of our daily lives. Outreach activities can he…
