Magnetic Rossby waves in the solar tachocline and Rieger-type periodicities

T. V. Zaqarashvili, M. Carbonell, R. Oliver +1

Apart from the 11-year solar cycle, another periodicity around 155-160 days was discovered during solar cycle 21 in high energy solar flares, and its presence in sunspot areas and…

Acoustic oscillations in the field-free, gravitationally stratified Acoustic oscillations in the field-free, gravitationally stratified cavities under solar bipolar magnetic canopies

D. Kuridze, T. V. Zaqarashvili, B. M. Shergelashvili +1

The main goal is to study the dynamics of the gravitationally stratified, field-free cavities in the solar atmosphere, located under small-scale, cylindrical magnetic canopies, in…

Network Loop Oscillations with EIS/Hinode

A. K. Srivastava, D. Kuridze, T. V. Zaqarashvili +2

We analyze a time sequence of He II 256.32 angstrom images obtained with EIS/Hinode, sampling a small magnetic loop in magnetic network. Wavelet analysis indicates 11-min periodici…

Farley-Buneman Instability in the Solar Chromosphere

G. Gogoberidze, Y. Voitenko, S. Poedts +1

The Farley-Buneman instability is studied in the partially ionized plasma of the solar chromosphere taking into account the finite magnetization of the ions and Coulomb collisions.…
