Modelling stellar coronal magnetic fields [PDF]
Proceedings of the International Astronomical Union, 2010 Our understanding of the structure and dynamics of stellar coronae has changed dramatically with the availability of surface maps of both star spots and also magnetic field vectors.

Magnetic Fields in Stellar Jets [PDF]
The Astrophysical Journal, 2007 Although several lines of evidence suggest that jets from young stars are driven magnetically from accretion disks, existing observations of field strengths in the bow shocks of these flows imply that magnetic fields play only a minor role in the ...

Observations of Cool-Star Magnetic Fields [PDF]
Living Reviews in Solar Physics, 2012 Cool stars like the Sun harbor convection zones capable of producing substantial surface magnetic fields leading to stellar magnetic activity. The influence of stellar parameters like rotation, radius, and age on cool-star magnetism, and the importance ...

Measuring the magnetic fields in the chromospheres of low-mass stars [PDF]
Nature CommunicationsMagnetic fields in the upper atmospheres of solar-like stars are believed to provide an enormous amount of energy to power the hot coronae and drive large-scale eruptions that could impact the habitability of planetary systems around these stars. However,

Evolution of Stellar Magnetic Fields [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractStellar magnetic fields can reliably be characterized by several magnetic activity indicators, such as X-ray or radio luminosity. Physical processes leading to such emission provide important information on dynamic processes in stellar atmospheres and magnetic structuring.

Magnetic Fields and Stellar Evolution [PDF]
Symposium - International Astronomical Union, 1981 Magnetic fields are now observed or inferred in a wide variety of stellar objects. The class of early-type stars with strong large-scale fields extends from types B to F, with effective fields from 300 gauss up to several x 104 gauss (Borra and Landstreet 1980).

Magnetic fields and stellar oscillations
, 2018 Stars are fluid bodies in which pressure, buoyancy, rotation and magnetism provide the restoring forces for wave propagation. Constructive interference of these waves generates global modes of oscillation. With sufficiently precise photometry, stellar oscillations can be detected through the periodic variations they induce in a star's brightness ...

The Direct Effect of Toroidal Magnetic Fields on Stellar Oscillations: An Analytical Expression for the General Matrix Element [PDF]
, 2017 Where is the solar dynamo located and what is its modus operandi? These are still open questions in solar physics. Helio- and asteroseismology can help answer them by enabling us to study solar and stellar internal structures through global oscillations.

Multiple views of magnetism in cool stars [PDF]
, 2012 Magnetic fields are regarded as a crucial element for our understanding of stellar physics. They can be studied with a variety of methods which provide complementary - and sometimes contradictory - information about the structure, strength and dynamics ...
