Probing the Sunspot Atmosphere with Three-Minute Oscillations
A. S. Deres, S. A. Anfinogentov
We present a seismological method to probe the solar atmosphere above sunspot umbrae with three-minute oscillations. Our technique allows us to estimate both the vertical distance…
Algorithms of the Potential Field Calculation in a Three Dimensional Box
G. V. Rudenko, S. A. Anfinogentov
Calculation of the potential field inside a three-dimensional box with the normal magnetic field component given on all boundaries is needed for estimation of important quantities…
Magnetic Helicity Estimations in Models and Observations of the Solar Magnetic Field. Part III: Twist Number Method
Y. Guo, E. Pariat, G. Valori +7
We study the writhe, twist and magnetic helicity of different magnetic flux ropes, based on models of the solar coronal magnetic field structure. These include an analytical force-…
Casting the Coronal Magnetic Field Reconstruction Tools in 3D Using MHD Bifrost Model
Gregory D. Fleishman, Sergey Anfinogentov, Maria Loukitcheva +2
Quantifying coronal magnetic field remains a central problem in solar physics. Nowadays the coronal magnetic field is often modelled using nonlinear force-free field (NLFFF) recons…
