Magnetic Source Regions of Coronal Mass Ejections
Coronal mass ejection flare filament eruption
2010/9/16
The majority of flare activity arises in active regions which contain sunspots, while Coronal Mass Ejection (CME) activity can also originate from decaying active regions and even so-called quiet sola...
Helicity of Solar Active Regions from a Dynamo Model
MHD—Sun activity—Sun magnetic fields—sunspots
2010/9/16
We calculate helicities of solar active regions based on the idea that poloidal flux lines get wrapped around a toroidal flux tube rising through the convection zone, thereby giving rise to the helici...

Helioseismic Ring Analysis of CME Source Regions
Sun coronal mass ejections oscillations magnetic field
2009/5/6
We apply the ring diagram technique to source regions of
halo coronal mass ejections (CMEs) to study changes in acoustic mode
parameters before, during, and after the onset of CMEs.We find that CME

2009/5/6
We study the magnetic and velocity field evolution in the
two magnetically complex active regions NOAA 10486 and NOAA 10488
observed during October–November 2003.We have used the available data
to ...
