Kinematic active region formation in a three-dimensional solar dynamo model [PDF]

, 2013
We propose a phenomenological technique for modelling the emergence of active regions within a three-dimensional, kinematic dynamo framework. By imposing localized velocity perturbations, we create emergent flux tubes out of toroidal magnetic field at ...

Solar flux emergence : a three-dimensional numerical study [PDF]

, 2008
Flux is continually emerging on the Sun, making its way from the solar interior up into the atmosphere. Emergence occurs on small-scales in the quiet Sun where magnetic fragments emerge, interact and cancel and on large-scales in active regions where ...

From the Sun to the Earth: The 13 May 2005 Coronal Mass Ejection [PDF]

, 2010
We report the results of a multi-instrument, multi-technique, coordinated study of the solar eruptive event of 13 May 2005. We discuss the resultant Earth-directed (halo) coronal mass ejection (CME), and the effects on the terrestrial space environment ...

The investigation of quasi-separatrix layers in solar magnetic fields [PDF]

, 2011
The structure of the magnetic field is often an important factor in many energetic processes in the solar corona. To determine the topology of the magnetic field features such as null points, separatrix surfaces, and separators must be found.

The Origin and Early Evolution of a Bipolar Magnetic Region in the Solar Photosphere [PDF]

Astrophysical Journal, 2018
Finding the formation mechanisms for bipolar configurations of a strong local magnetic field under control of the relatively weak global magnetic field of the Sun is a key problem of the physics of solar activity.

Properties of mass-loading shocks, 2. Magnetohydrodynamics [PDF]

, 1992
The one-dimensional magnetohydrodynamics of shocked flows subjected to significant mass loading are considered. Recent observations at comets Giacobini-Zinner and Halley suggest that simple nonreacting MHD is an inappropriate description for active ...

The Contribution of Solar Magnetic Regions to the Residual Meridional and Zonal Flows

The Astrophysical Journal
We estimate the contributions to the solar-cycle variation of solar meridional and zonal flows near the surface expected solely from local magnetic regions.
