Are the Magnetic Fields Radial in the Solar Polar Region?

چکیده

Abstract We investigate the orientation of photospheric magnetic fields in solar polar region using observations from Helioseismic and Magnetic Imager (HMI). Inside small patches significant polarization, inferred field vectors at 1″ scale appear to systematically deviate radial direction. Most tilt toward pole; all are more inclined plane sky compared vector. These results, however, depend on “filling factor” f that characterizes unresolved structures. The default, uninformative ≡ 1 for HMI will incur larger inclination less than < 1. observed trend may be a systematic bias inherent limited resolution.

Different magnetic features between solar polar and equatorial magnetic fields

Solar polar and equatorial photospheric (FeIλ5324.19 Å line) magnetic fields have been observed using the vector video magnetograph at Huairou Solar Observing Station of Beijing Astronomical Observatory. It is found from our observations that the magnetic fields of small-scale magnetic features near the solar poles are stronger than in quiet equatorial regions near the limb, and that strong pol...

Magnetic fields in the solar photosphere.

Recent high-resolution observations of the surface of the Sun have revealed the fine structure of a vast array of complex photospheric magnetic features. Observations of these magnetic field structures have already greatly enhanced our theoretical understanding of the interactions between magnetic fields and turbulent convection, and future photospheric observations will inevitably present new ...
