Solar Magnetic Fields
Solar Magnetic Fields
2011/9/28
This review provides an introduction to the generation and evolution of the Sun's magnetic field, summarising both observational evidence and theoretical models. The eleven year solar cycle, which is ...
Observational Study of Solar Magnetic Active Phenomena
Sun: activity flares magnetic fields
2010/9/17
The electric current separated into two parts reflected the quantative properties of heterogeneity and chirality of magnetic field, and defined them as the shear and twist components of current. We an...
Initiation of CMEs by Magnetic Flux Emergence
Sun: corona coronal mass ejections magnetic fields magnetohydrodynamics flux emergence
2010/9/16
The initiation of solar Coronal Mass Ejections (CMEs) is studied in the framework of numerical magnetohydrodynamics (MHD).The initial CME model includes a magnetic flux rope in spherical, axisymmetric...
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...
Role of Magnetic Carpet in Coronal Heating
Sun—corona—magnetic field—magnetic carpet—reconnection
2010/9/16
One of the fundamental questions in solar physics is how the solar corona maintains its high temperature of several million Kelvin above photosphere with a temperature of 6000 K.
Observations show th...
Seismic Study of Magnetic Field in the Solar Interior
Sun oscillations interior magnetic field
2010/9/15
Magnetic field in the solar interior contributes to the even order splitting coefficients, but it is not possible to separate the effect of magnetic field from those due to other deviations from spher...
Since the structuring and variability of the Sun and other stars are governed by magnetic fields, much of present-day stellar physics centers around the measurement and understanding of the magnetic f...

The Sun's magnetic field environment astronauts
2010/9/21
The Sun's extended magnetic field provides a vital shield for astronauts; without it they would be left exposed to potentially deadly cosmic rays entering in from outside the solar system. Now, a grou...

The Heliospheric Magnetic Field over the Hale Cycle
Heliospheric Magnetic Field Hale Cycle coronal mass ejections
2009/5/27
The concept that open magnetic flux of the Sun (rooted with one and only one footpoint at the Sun) is a conserved quantity is taking root in the heliospheric community. Observations show that the Sun'...
