Solar coronal dimmings have been observed extensively in the past two decades and are believed to have close association with coronal mass ejections (CMEs). Recent study found that coronal dimming is the only signature that could differentiate powerf

On the role of asymmetries in the reversal of the solar magnetic field

Publikováno v: Proceedings of the International Astronomical Union. 8:75-80

We study how the solar magnetic field evolves from antisymmetric (dipolar) to symmetric (quadrupolar) state during the course of its 11-yr cycle. We show that based on equatorial symmetries of the induction equation, flux transport solar mean field d

Dipolar and Quadrupolar Magnetic Field Evolution over Solar Cycles 21, 22, and 23

Autor: J. T. Hoeksema, M. L. Derosa, Allan Sacha Brun

Publikováno v: Proceedings of the International Astronomical Union. 6:94-101

Time series of photospheric magnetic field maps from two observatories, along with data from an evolving surface-flux transport model, are decomposed into their constituent spherical harmonic modes. The evolution of these spherical harmonic spectra r

Coronal radiation belts

Autor: S. F. N. Frewen, Hugh S. Hudson, Alexander L. MacKinnon, M. L. DeRosa

The magnetic field of the solar corona has a large-scale dipole character, which maps into the bipolar field in the solar wind. Using standard representations of the coronal field, we show that high-energy ions can be trapped stably in these large-sc
