Galactic Cosmic Rays at Mars and Venus: Temporal Variations from Hours to Decades Measured as the Background Signal of Onboard Micro-Channel Plates
Yoshifumi Futaana, Manabu Shimoyama, Martin Wieser +8
A Micro-Channel Plate (MCP) is a widely used component for counting particles in space. Using the background counts of MCPs on Mars Express and Venus Express orbiters operated over…
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 wind dynamics around a comet: The paradigmatic inverse-square-law model
Melaine Saillenfest, Benoît Tabone, Etienne Behar
Aims. Observations of solar protons near comet 67P/Churyumov-Gerasimenko (67P) by the Rosetta spacecraft can be modelled by the planar motion in an effective magnetic field proport…
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…
Mass-loading of the solar wind at 67P/Churyumov-Gerasimenko -- Observations and modelling
E. Behar, J. Lindkvist, H. Nilsson +4
Context. The first long-term in-situ observation of the plasma environment in the vicinity of a comet, as provided by the European Rosetta spacecraft. Aims. Here we offer character…
Mass loading at 67P/Churyumov-Gerasimenko: a case study
E. Behar, H. Nilsson, G. Stenberg Wieser +3
We study the dynamics of the interaction between the solar wind ions and a partially ionized atmosphere around a comet, at a distance of 2.88 AU from the sun during a period of low…
Dawn-dusk asymmetry induced by the Parker spiral angle in the plasma dynamics around comet 67P/Churyumov-Gerasimenko
E. Behar, B. Tabone, H. Nilsson
When interacting, the solar wind and the ionised atmosphere of a comet exchange energy and momentum. Our aim is to understand the influence of the average Parker spiral configurati…
Solar wind dynamics around a comet - A 2D semi-analytical kinetic model
E. Behar, B. Tabone, M. Saillenfest +5
We aim at analytically modelling the solar wind proton trajectories during their interaction with a partially ionised cometary atmosphere, not in terms of bulk properties of the fl…
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…
