The magnetic Sun.
The nature of our star, the Sun, is dominated by its complex and variable magnetic fields. It is the purpose of this paper to review the fundamental nature of our magnetic Sun by outlining the most basic principles behind the way the Sun works and how its fields are generated, and to examine not only the historical observations of our magnetic star, but, in particular, to study the wonderful ob...

متن کاملMagnetic flux transport on the sun.
Although most of the magnetic flux observed on the sun originates in the low-latitude sunspot belts, this flux is gradually dispersed over a much wider range of latitudes by supergranular convective motions and meridional circulation. Numerical simulations show how these transport processes interact over the 11-year sunspot cycle to produce a strong "topknot" polar field, whose existence near s...
متن کاملMagnetic field emergence in quiet Sun granules
Aims. We describe a new form of small-scale magnetic flux emergence in the quiet Sun. This process seems to take vertical magnetic fields from the solar interior to the photosphere, where they appear above granular convection cells. Methods. High-cadence time series of spectropolarimetric measurements obtained by Hinode in a quiet region near disk center are analyzed. We extract line parameters...
متن کاملThe Strength of Quiet Sun Magnetic Fields
We present new quantitative measurements of magnetic fields on the quiet Sun. The object was (a) to measure magnetic field strengths, and (b) to test the “kilogauss model,” which posits that the apparently weak fields are actually subtelescopic knots of kilogauss fields with small filling factors. We used a new arrangement we call the spectro-videomagnetograph (SPVMG), which applies the videoma...
