Evidence of global periodicity in PSP data: can they be linked to long-period oscillations in solar active regions?
G. Dumbadze, B. M. Shergelashvili, M. Khodachenko +4
The presence of coherent oscillatory signatures in Parker Solar Probe SWEAP datasets, identified through a series of spectral analyses, is addressed, and their possible connection…
Polytropic stellar wind models with strongly localized heating
L. Westrich, B. Shergelashvili, H. Fichtner +1
Polytropic models of stellar winds remain to be useful tools because they allow for a simple description of the energy balance of the expanding plasma without explicitly specifying…
Wide-band fluctuations of solar active regions probed with SHARP magnetograms
G. Dumbadze, B. M. Shergelashvili, M. L. Khodachenko +1
The power spectra of the fluctuation noise of the solar active region (AR) areas and magnetic fluxes sequentially observed in time contain information about their geometrical featu…
Categorization model of moving small-scale intensity enhancements in solar active regions
B. M. Shergelashvili, E. Philishvili, S. Buitendag +2
The small-scale moving intensity enhancements remotely observed in the extreme ultraviolet images of the solar active regions, which we refer to as active region moving campfires (…
Eigenspectra of solar active region long-period oscillations
G. Dumbadze, B. M. Shergelashvili, S. Poedts +3
We studied the low-frequency h (long-period h) oscillations of active regions (ARs). The investigation is based on an analysis of a time series…
Case study on the identification and classification of small-scale flow patterns in flaring active region
E. Philishvi, B. M. Shergelashvili, S. Buitendag +3
We propose a novel methodology to identity flows in the solar atmosphere and classify their velocities as either supersonic, subsonic, or sonic. The proposed methodology consists o…
