The Sun's Global Photospheric and Coronal Magnetic Fields: Observations and Models
Living Reviews in Solar Physics, 2012 In this review, our present day understanding of the Sun’s global photospheric and coronal magnetic fields is discussed from both observational and theoretical viewpoints. Firstly, the large-scale properties of photospheric magnetic fields are described,

The Astrophysical Journal, 2023 The magnetic activity of a star—which modulates the stellar wind outflow—shapes the immediate environments of orbiting (exo)planets and induces atmospheric loss, thereby impacting their habitability.

Search for magnetic fields in particle-accelerating colliding-wind binaries [PDF]
, 2014 Some colliding-wind massive binaries, called particle-accelerating colliding-wind binaries (PACWB), exhibit synchrotron radio emission, which is assumed to be generated by a stellar magnetic field.

Doppler Imaging of stellar magnetic fields [PDF]
Astronomy & Astrophysics, 2002 We present an investigation of the magnetic field geometries and inhomogeneous distribution of chemical elements in the atmospheres of peculiar A and B stars. Our study combines high-quality spectroscopic and spectropolarimetric stellar observations with the development and application of novel techniques for theoretical interpretation of the shapes ...

Catalog of Magnetic White Dwarfs with Hydrogen Dominated Atmospheres
The Astrophysical Journal, 2023 White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three physical parameters interact with each other and with other stellar features,

First Magnetic Field Detection on a Class I Protostar [PDF]
, 2009 Strong stellar magnetic fields are believed to truncate the inner accretion disks around young stars, redirecting the accreting material to the high latitude regions of the stellar surface.

Recent Measurements of Stellar Magnetic Fields [PDF]
Symposium - International Astronomical Union, 1991 High resolution, high S/N spectra have been successfully modeled to yield information on the magnetic properties of cool stars for some 15 years now. These analyses yield estimates of the intensity weighted surface filling factor of active regions, f, and the mean unsigned field strength in these regions), B.

, 2007 Despite the influence of magnetic fields on the structure and evolution of stars is largely demonstrated from the theoretical point of view, their observational evidence in non-degenerated stars is still rather scanty and mainly circumscribed to bright ...

18. Stellar magnetic fields [PDF]
Symposium - International Astronomical Union, 1958 A report is given of a ten-year observational program directed toward the discovery and investigation of the magnetic fields of stars through the Zeeman effect in their spectra. The emphasis has been on the sharp-line stars of type A, of which ten have been found to show irregular magnetic fluctuations without reversal of polarity, ten others to ...
