Prominence instability and CMEs triggered by massive coronal rain in the solar atmosphere
Z. Vashalomidze, T. V. Zaqarashvili, V. Kukhianidze +3
Triggering process for prominence instability and consequent CMEs is not fully understood. Prominences are maintained by the Lorentz force against the gravity, therefore reduction…
Magneto-Rossby waves in the solar tachocline and the annual variations in solar activity
Tamar Gachechiladze, Teimuraz V. Zaqarashvili, Eka Gurgenashvili +4
Annual oscillations have been detected in many indices of solar activity during many cycles. Recent multi spacecraft observations of coronal bright points revealed slow retrograde…
Quasi-oscillatory dynamics observed in ascending phase of the flare on March 6, 2012
E. Philishvili, B. M. Shergelashvili, T. V. Zaqarashvili +5
Context. The dynamics of the flaring loops in active region (AR) 11429 are studied. The observed dynamics consist of several evolution stages of the flaring loop system during both…
Long-period oscillations of active region patterns: least-squares mapping on second-order curves
G. Dumbadze, B. M. Shergelashvili, V. Kukhianidze +6
Active regions (ARs) are the main sources of variety in solar dynamic events. Automated detection and identification tools need to be developed for solar features for a deeper unde…
Rieger-type periodicity during solar cycles 14-24: estimation of dynamo magnetic field strength in the solar interior
Eka Gurgenashvili, Teimuraz Zaqarashvili, Vasil Kukhianidze +6
Solar activity undergoes a variation over time scales of several months known as Rieger-type periodicity, which usually occurs near maxima of sunspot cycles. An early analysis show…
Dynamics of a solar prominence tornado observed by SDO/AIA on 2012 November 7-8
I. Mghebrishvili, T. V. Zaqarashvili, V. Kukhianidze +4
We study the detailed dynamics of a solar prominence tornado using time series of 171, 304, 193 and 211 Å spectral lines obtained by Solar Dynamics Observatory/ Atmospheric Imaging…
Formation and evolution of coronal rain observed by SDO/AIA on February 22, 2012
Z. Vashalomidze, V. Kukhianidze, T. V. Zaqarashvili +5
The formation and dynamics of coronal rain are currently not fully understood. Coronal rain is the fall of cool and dense blobs formed by thermal instability in the solar corona to…
