On the robustness of the pendulum model for large-amplitude longitudinal oscillations in prominences
M. Luna, J. Terradas, E. Khomenko +2
Large-amplitude longitudinal oscillations (LALOs) in prominences are spectacular manifestations of the solar activity. In such events nearby energetic disturbances induce periodic…
Fast-to-Alfvén Mode Conversion Mediated by Hall Current. I. Cold Plasma Model
Paul S. Cally, Elena Khomenko
The photospheric temperature minimum in the Sun and solar-like stars is very weakly ionized, with ionization fraction as low as . In galactic star forming regions, …
On the Source of Propagating Slow Magneto-acoustic Waves in Sunspots
S. Krishna Prasad, D. B. Jess, Elena Khomenko
Recent high-resolution observations of sunspot oscillations using simultaneously operated ground- and space-based telescopes reveal the intrinsic connection between different layer…
Evershed flow observed in neutral and singly ionized iron lines
E. Khomenko, M. Collados, N. Shchukina +1
The amplitudes of the Evershed flow are measured using pairs of carefully selected FeI and FeII spectral lines located close in wavelength and registered simultaneously. A sunspot…
On the nature of transverse coronal waves revealed by wavefront dislocations
A. López Ariste, M. Luna, I. Arregui +2
Coronal waves are an important aspect of the dynamics of the plasma in the corona. Wavefront dislocations are topological features of most waves in nature and also of magnetohydrod…
Beyond MHD: modeling and observation of partially ionized solar plasma processes
Elena Khomenko
The temperature and density conditions in the magnetized photosphere and chromosphere of the Sun lead to a very small degree of atomic ionization. In addition, at particular height…
