Polar cap arcs from the magnetosphere to the ionosphere: kinetic modelling and observations by Cluster and TIMED [PDF]
Annales Geophysicae, 2012 On 1 April 2004 the GUVI imager onboard the TIMED spacecraft spots an isolated and elongated polar cap arc. About 20 min later, the Cluster satellites detect an isolated upflowing ion beam above the polar cap.

Phase-space tomography in magnetically confined plasmas [PDF]
, 2023 0000-0001-5669-1937In this paper, a tomography approach aiming at reconstructing a phase-space structure is proposed. For the phase-space resolved diagnostic system, a signal must be decomposed in real-space, velocity-space, and time; therefore, it is ...

Dusty plasmas: from Saturn’s rings to semiconductor processing devices
Advances in Physics: X, 2021 Dusty plasmas are plasmas containing solid particles in the size range of about 10 nm—10 μm. The particles acquire an electrical charge by collecting electrons and ions from the plasma, or by photo-electron emission if they are exposed to UV radiation ...

Electrostatic Solitary Waves in Electronegative Martian Plasma
The Astrophysical JournalThe solar wind interacts with planetary magnetospheres, generating plasma waves in both the upstream region and the magnetospheric environment. Mars, lacking an inherent magnetic field, has an induced magnetosphere formed through solar wind interaction ...

Magnetic Island Structures Associated with Kinetic Alfvén Solitary Wave in Two-fluid Plasma
The Astrophysical JournalWe investigate the formation of magnetic islands and the onset of tearing instability within kinetic Alfvén solitary waves in a two-fluid space plasma. These localized structures, featuring internal magnetic shear, naturally support magnetic reconnection
