Alfvénic fluctuations in the expanding solar wind: Formation and radial evolution of spherical polarization
Hellinger, P.; Matteini, L.; Horbury, T. S. +7 more
We investigate properties of large-scale solar wind Alfvénic fluctuations and their evolution during radial expansion. We assume a strictly radial background magnetic field B ∥ R, and we use two-dimensional hybrid (fluid electrons, kinetic ions) simulations of balanced Alfvénic turbulence in the plane orthogonal to B; the simulated plasma evolves …
Kinetic numerical scaling of Alfven cyclotron instability in non-thermal solar wind plasmas
Shahzad, Muhammad Ahsan; Aman-ur-Rehman; Bilal, Muhammad +3 more
Linear plasma kinetic theory for a non-thermal, magnetized, homogeneous, and collisionless plasma is incorporated to study Alfvén cyclotron instability (ACI) driven by the ion/proton perpendicular temperature anisotropy (T⊥p/T∥p>1) ( ⊥, ∥ symbols designate directions perpendicular and parallel to ambient magnetic field, respectively), and the w…
Role of nonlinear structures and associated turbulence generation dayside magnetosphere reconnection sites
Sharma, R. P.; Pathak, Neha; Sharma, Suresh C. +1 more
A numerical simulation is implemented to investigate the role of whistler wave in the presence of the ponderomotive force-driven density modification and the magnetic field perturbation due to preexisting magnetic islands. The dynamical equation governing the whistler waves is derived and solved using numerical methods to assess their role. The si…
