Bifractal Behavior of Solar Supergranulation and Magnetic Activity

Rajani G., Sowmya G. M., Paniveni U., Srikanth R.

Acta Astronomica

2023

Vol. 73, No. 2

187--195

We study the complexity and scale of the supergranular network across the 23rd solar cycle, using the Ca II K digitized intensitygrams from the Kodaikanal Solar Observatory (KSO). Enhancing our previous data and refining our data analysis, we study supergranular fractal dimension as a function of cell size. We find that across the cycle phases, the cells show a bifractal behavior, with approximately half the larger cells in the studied scale range showing a slightly greater fractal dimension than the smaller cells. We also study the discrepancy between supergranular scale as determined by direct inspection methods (around 17 Mm) and autocorrelation (around 30 Mm), and attribute this to a preferential selection of well defined cells in the former case.

Dynamical Evolution of Magnetic Flux Tube in the Solar Convective Zone

Samujłło M.

Acta Astronomica

1998

Vol. 48, No. 4

789--802

We present computations of nonlinear development of the kink instability in a horizontal magnetic flux tube lying initially in the deep convective zone. Obtained results are compared with an independent solution of the problem obtained formerly by Moreno-Insertis (1986). Consistency of solutions allows to evaluate the numerical code, in particular the treatment of the energy balance which is different than that of Moreno-Insertis.
