An investigation of helicity injection by photospheric shear motions is presented for two active regions, NOAA 11158 and 11166, using LOS magnetic field observations obtained from the Helioseismic and...
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...

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...
Concept of magnetic/current helicity was introduced to solar
physics about 15 years ago. Earlier studies led to discovery of such fundamental
properties as hemispheric helicity rule, and role of he...

太阳螺度 讨论会 Helicity Thinkshop Solar Physics
2009/3/31
Magnetic helicity has been intensively studied concerning the observation, dynamo theory and many other relevant academic areas. This meeting would like to invite solar physicists who are active in th...
