Solar magnetic fields as revealed by Stokes polarimetry [PDF]
The Astronomy and Astrophysics Review, 2013 Observational astrophysics started when spectroscopy could be applied to astronomy. Similarly, observational work on stellar magnetic fields became possible with the application of spectro-polarimetry.

History of Solar Magnetic Fields Since George Ellery Hale [PDF]
, 2015 As my own work on the Sun’s magnetic field started exactly 50 years ago at Crimea in the USSR, I have been a participant in the field during nearly half the time span since Hale’s discovery in 1908 of magnetic fields in sunspots.

The crucial role of surface magnetic fields for the solar dynamo [PDF]
Science, 2015 Sunspot cycle driven by linked fields Sunspots indicate magnetic flux emerging at the Sun's surface. Sunspots change over an 11-year time scale, which depends on the behavior of the probable magnetic dynamo within. Cameron et al.

A Statistical Study on Force-Freeness of Solar Magnetic Fields in the Photosphere [PDF]
Publications Astronomical Society of Australia, 2012 It is an indisputable fact that solar magnetic fields are force-free in the corona, where force-free fields mean that current and magnetic fields are parallel and there is no Lorentz force in the fields.

Temporal Behaviors of Magnetic Helicity Injections by Self and Mutual Sunspot Rotations
The Astrophysical Journal, 2023 Magnetic helicity is a physical parameter used to quantify the complexity of magnetic fields, providing an indication of the energy state in the coronal magnetic structure.

The Evolution of Surface Magnetic Fields in Young Solar-type Stars [PDF]
Proceedings of the International Astronomical Union, 2013 Surface rotation rates of young solar-type stars display drastic changes at the end of the pre-main sequence through the early main sequence. This may trigger corresponding changes in the magnetic dynamos operating in these stars, which ought to be ...

KamLAND, solar antineutrinos, and the solar magnetic field [PDF]
Physical Review D, 2003 In this work the possibility of detecting solar electron antineutrinos produced by a solar core magnetic field from the KamLAND recent observations is investigated. We find a scaling of the antineutrino probability with respect to the magnetic field profile in the sense that the same probability function can be reproduced by any profile with a suitable

The evolution of a spot–spot-type solar active region which produced a major solar eruption
Frontiers in Astronomy and Space Sciences, 2023 Solar active regions are the main sources of large solar flares and coronal mass ejections. It is found that the active regions producing large eruptions usually show compact, highly sheared polarity inversion lines.

On the Origin of the Photospheric Magnetic Field
The Astrophysical Journal, 2022 This article presents results that challenge the paradigms that (1) the convection zone is the source of the radial magnetic field in the photosphere and (2) that coronal currents are neutralized from the perspective of the photosphere.
