The Origin of Net Electric Currents in Solar Active Regions
There is a recurring question in solar physics regarding whether or not electric currents are neutralized in active regions (ARs). This question was recently revisited using three-dimensional (3D) magnetohydrodynamic (MHD) numerical simulations of magnetic flux emergence into the solar atmosphere. Such simulations showed that flux emergence can generate a substantial net current in ARs. Other s...
متن کاملVertical Lorentz Force and Cross-field Currents in the Photospheric Magnetic Fields of Solar Active Regions
We demonstrate that the vertical Lorentz force and a corresponding lower limit of the cross-field electric current density can be calculated from vector magnetograms of solar active regions obtained at a single height in the solar atmosphere, provided that the vertical gradient of the magnetic field strength is known at this height. We use a predicted vertical magnetic field gradient derived fr...
متن کاملEvolution of force-free electric currents in the solar atmosphere
The new 3-D numerical model studying evolution of force-free electric currents in the solar atmosphere is presented. The initial dipole magnetic field is considered in a simplified active region. Starting from a low electric current, which penetrates the photosphere, and increasing the current intensity, the path of force-free electric current and the corresponding magnetic field are computed. ...

15 صفحه اولThe Magnetic Classification of Solar Active Regions
The purpose of this letter is to address a blind-spot in our knowledge of solar active region statistics. To the best of our knowledge there are no published results showing the variation of the Mount Wilson magnetic classifications as a function of solar cycle based on modern observations. We show statistics for all active regions reported in the daily Solar Region Summary from 1992 January 1 ...
