Three-dimensional MHD wave propagation near a coronal null point: a new wave mode decomposition approach
N. Yadav, Rony Keppens, B. Popescu Braileanu
We present a new MHD wave decomposition method that overcomes the limitations of existing wave identification methods. Our method allows to investigate the energy fluxes in differe…
Effects of ambipolar diffusion on waves in the solar chromosphere
Beatrice Popescu Braileanu, Rony Keppens
The chromosphere is a partially ionized layer of the solar atmosphere, the transition between the photosphere where the gas motion is determined by the gas pressure and the corona…
Simulations of the Biermann battery mechanism in two-fluid partially ionised plasmas
David Martínez-Gómez, Beatrice Popescu Braileanu, Elena Khomenko +1
In the absence of an initial seed, the Biermann battery term of a non-ideal induction equation acts as a source that generates weak magnetic fields. These fields are then amplified…
Two-fluid simulations of Rayleigh-Taylor instability in a magnetized solar prominence thread II. Effects of collisionality
B. Popescu Braileanu, V. S. Lukin, E. Khomenko +1
In this work, we explore the dynamical impacts and observable signatures of two-fluid effects in the parameter regimes when ion-neutral collisions do not fully couple the neutral a…
Two-fluid simulations of Rayleigh-Taylor instability in a magnetized solar prominence thread. I. Effects of prominence magnetization and mass loading
B. Popescu Braileanu, V. S. Lukin, E. Khomenko +1
Solar prominences are formed by partially ionized plasma with inter-particle collision frequencies generally warranting magnetohydrodynamic treatment. In this work, we explore the…
Two-fluid simulations of waves in the solar chromosphere II. Propagation and damping of fast magneto-acoustic waves and shocks
B. Popescu Braileanu, V. S. Lukin, E. Khomenko +1
Waves and shocks traveling through the solar chromospheric plasma are influenced by its partial ionization and weak collisional coupling, and may become susceptible to multi-fluid…
