Equatorially trapped Rossby waves in radiative stars
M. Albekioni, T. V. Zaqarashvili, V. Kukhianidze +2
Observations by recent space missions reported the detection of Rossby waves (r-modes) in light curves of many stars (mostly A, B, and F spectral types) with outer radiative envelo…
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…
North-south asymmetry in Rieger-type periodicity during solar cycles 19-23
Eka Gurgenashvili, Teimuraz V. Zaqarashvili, Vasil Kukhianidze +4
Rieger-type periodicity has been detected in different activity indices over many solar cycles. It was recently shown that the periodicity correlates with solar activity having a s…
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…
