Kinetic Electrostatic Waves and their Association with Current Structures in the Solar Wind
D. B. Graham, Yu. V. Khotyaintsev, A. Vaivads +21
A variety of kinetic waves develop in the solar wind. The relationship between these waves and larger-scale structures, such as current sheets and ongoing turbulence remain a topic…
Density Fluctuations Associated with Turbulence and Waves: First Observations by Solar Orbiter
Yu. V. Khotyaintsev, D. B. Graham, A. Vaivads +21
We use the plasma density based on measurements of the probe-to-spacecraft potential in combination with magnetic field measurements by MAG to study fields and density fluctuations…
The Science Case for a Titan Flagship-class Orbiter with Probes
Conor A. Nixon, James Abshire, Andrew Ashton +36
We outline a flagship-class mission concept focused on studying Titan as a global system, with particular emphasis on the polar regions. Investigating Titan from the unique standpo…
The evolution of the electron number density in the coma of comet 67P at the location of Rosetta from 2015 November through 2016 March
Erik Vigren, Niklas J. T. Edberg, Anders I. Eriksson +6
A comet ionospheric model assuming the plasma to move radially outward with the same bulk speed as the neutral gas and not being subject to severe reduction through dissociative re…
