Continuous upflows and sporadic downflows observed in active regions
Sun : corona – Sun: transition region – Sun : UV radiation

We present a study of the temporal evolution of coronal loops in active regions and its implications for the dynamics in coronal loops. We analyzed images of the Atmospheric Imaging Assembly (AIA) on ...
Quasi periodic oscillations of solar active regions in connection with their flare activity - NoRH observations
Oscillations, Solar Radio Emission Radio Bursts, Association with Flares

The sunspot-associated sources at the frequency of 17 GHz give information on plasma parameters in the regions of magnetic field about B=2000 G at the level of the chromosphere-corona transition regio...
Uncovering Mechanisms of Coronal Magnetism via Advanced 3D Modeling of Flares and Active Regions
Uncovering Mechanisms of Coronal Magnetism 3D Modeling of Flares Active Regions

The coming decade will see the routine use of solar data of unprecedented spatial and spectral resolution, time cadence, and completeness. To capitalize on the new (or soon to be available) facilities...
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...
Magnetic and Velocity Field Variations in the Active Regions NOAA 10486 and NOAA 10488
Sun magnetogram—Sun Dopplergram—Sun flare
2010/9/15
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 exa...
