Advances in mean-field dynamo theories

, 2012
We give a short introduction to the subject and review advances in understanding the basic ingredients of the mean-field dynamo theory. The discussion includes the recent analytic and numerical work in developments for the mean electromotive force of the

The Origin of Sequential Chromospheric Brightenings

, 2017
Sequential chromospheric brightenings (SCBs) are often observed in the immediate vicinity of erupting flares and are associated with coronal mass ejections. Since their initial discovery in 2005, there have been several subsequent investigations of SCBs.

Large Scale Soft X-ray Loops And Their Magnetic Chirality In Both Hemispheres

, 2010
The magnetic chirality in solar atmosphere has been studied based on the soft X-ray and magnetic field observations. It is found that some of large-scale twisted soft X-ray loop systems occur for several months in the solar atmosphere, before the ...

Simulating the Solar Corona with Multiple Solar Photospheric Magnetic Maps during the 2024 April 8 Total Solar Eclipse

The Astrophysical Journal
The 2024 April 8 total solar eclipse provides a unique opportunity to study the solar corona. This work presents our simulations of the solar corona at the time of the eclipse based on magnetohydrodynamic modeling performed with the Alfvén Wave Solar ...

Search for torsional oscillations in isolated sunspots

, 2017
In this work we seek evidence for global torsional oscillations in alpha sunspots. We have used long time series of continuum intensity and magnetic field vector maps from the Helioseismic and Magnetic Imager (HMI) instrument on board the Solar Dynamics ...
