Solar magnetic fields

Space Science Reviews, 1964
This paper is a review of our observational knowledge on solar magnetic fields. In Section 1 we make an attempt to summarize all observations of the general magnetic field (m.f.) of the Sun. Section 2 deals with the local m.f. at low latitudes and their connection with some features on the disk. The m.f.

Magnetic fields in the solar photosphere

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008
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 ...

Intermittency of the Solar Magnetic Field and Solar Magnetic Activity Cycle

Solar Physics, 2017
Small-scale solar magnetic fields demonstrate features of fractal intermittent behavior, which requires quantification. For this purpose we investigate how the observational estimate of the solar magnetic flux density \(B\) depends on resolution \(D\) in order to obtain the scaling \(\ln B_{D} = - k \ln D +a\) in a reasonably wide range. The quantity \(

Magnetic fields and the solar corona

Solar Physics, 1970
Coronal magnetic fields calculated by the methods developed in Paper I (Altschuler and Newkirk, 1969) and the empirical description of the solar corona of November 1966 derived in Paper II (Newkirket al., 1970) are combined in order to investigate what connection exists between the magnetic fields and the density structure of the corona.

Elements and Patterns in the Solar Magnetic Field

Annual Review of Astronomy and Astrophysics, 1987
and the non thermal processes in th e solar atmosphere indicate the importance of mag netic fields in turbulent cosmical bodies. We are now aware that magnetic processes also occur in other stars, in protostars, in supernova remnants, in gaseous disks of galaxies, in accretion disks around compact stars, and in active nuclei of galaxies.

SOLAR MAGNETIC FIELDS

1966
Abstract : A study was conducted of the correspondence of photospheric magnetic fields with structures and transient phenomena observed in the chromosphere. The primary data used were isogauss maps constructed from the Mt. Wilson daily, full disk magnetograms for the period 1959 through 1962, and three fine-scan magnetograms made on 6 July 1965.
