Detecting the solar new magnetic flux regions on the base of vector magnetograms
Golovko, A. A.; Salakhutdinova, I. I.
To understand better the origin of CME and other non-stationary processes, the detailed information about emerging flux regions must be known. The advanced method of mapping emerging magnetic flux regions through the multifractal segmentation of vector photospheric magnetograms, is created. It is free from influence of effects of projection. Maps …
Non-force-free extrapolation of solar coronal magnetic field using vector magnetograms
Gary, G. A.; Hu, Qiang; Büchner, J. +2 more
We report our recent improvement in non-force-free extrapolation of coronal magnetic field, using vector magnetograms. Based on the principle of minimum (energy) dissipation rate (MDR), a generally non-force-free magnetic field solution is expressed as the superposition of one potential field and two (constant-[alpha]) linear force-free fields, wi…
