Decayless kink waves
Decayless kink waves
Study of decayless kink waves in active region coronal loops. our results suggest that none of the commonly suspected sources proposed to drive decayless oscillations in active-region loops seem to be operating here, and therefore the search for that elusive wave driver needs to continue.
Sunspots & solar cycle
Sunspots & solar cycle
In this study, we found that different properties of the sunspot cycles depend on the sunspot sizes. The “odd–even rule” double peaks during the cycle maxima and the long-term periodicities in the area data are found to be present for specific sunspot sizes and are absent or not so prominent in other size ranges.
