Ion-scale transition of plasma turbulence: Pressure-strain effect
Petr Hellinger, Victor Montagud-Camps, Luca Franci +4
We investigate properties of solar wind-like plasma turbulence using direct numerical simulations. We analyze the transition from large, magnetohydrodynamic (MHD) scales to the ion…
Asteroseismic Signature of a Large Active Region
Emanuele Papini, Laurent Gizon
Axisymmetric magnetic activity on the Sun and Sun-like stars increases the frequencies of the modes of acoustic oscillation. However, it is unclear how a corotating patch of activi…
Spectral anisotropies and intermittency of plasma turbulence at ion kinetic scales
Simone Landi, Luca Franci, Emanuele Papini +3
By means of three dimensional high-resolution hybrid simulations we study the properties of the magnetic field spectral anisotropies near and beyond ion kinetic scales. By using bo…
Three-dimensional local anisotropy of velocity fluctuations in the solar wind
Andrea Verdini, Roland Grappin, Olga Alexandrova +4
We analyse velocity fluctuations in the solar wind at magneto-fluid scales in two datasets, extracted from Wind data in the period 2005-2015, that are characterised by strong or we…
Simulating acoustic waves in spotted stars
Emanuele Papini, Aaron C. Birch, Laurent Gizon +1
Acoustic modes of oscillation are affected by stellar activity, however it is unclear how starspots contribute to these changes. Here we investigate the nonmagnetic effects of star…
