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 ...

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops

The Astrophysical Journal
Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (

Spectroscopic Study of Heating Distributions and Mechanisms Using Hinode/EIS

The Astrophysical Journal
Heating distributions along coronal loops are obtained from spectroscopic data with the Hinode/EUV Imaging Spectrometer. The loop half-lengths L _half are in the range of 24–107 Mm for our analysis of 18 loops.

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.

Understanding the Magnetic Field and Plasma-β along Umbral Fan Loops Traced Using 3 Minute Slow Waves

The Astrophysical Journal Letters
Plasma- β is an important fundamental physical quantity in solar plasma physics, which determines the dominating process in the solar atmosphere, i.e., magnetic or thermodynamic processes. Here, for the first time, we provide variations of magnetic field

Relating near-Earth observations of an interplanetary coronal mass ejection to the conditions at its site of origin in the solar corona [PDF]

, 2005
A halo coronal mass ejection (CME) was detected on January 20, 2004. We use solar remote sensing data (SOHO, Culgoora) and near-Earth in situ data (Cluster) to identify the CME source event and show that it was a long duration flare in which a magnetic ...

Solar influences in the heliosphere: understanding coronal mass ejections and their associated magnetic clouds [PDF]

, 2011
Coronal mass ejections (CMEs) are large-scale explosions on the Sun that expel plasma and magnetic field into the heliosphere. The interplanetary counterparts of CMEs, termed interplanetary CMEs (ICMEs), are often directly observed by spacecraft ...
