Stellar Magnetic Fields

2005
Stellar magnetic fields are directly detected or inferred across the whole Hertzsprung-Russell Diagram. Attention in this chapter is concentrated on premain sequence and on late- and early-type main sequence stars, with some discussion also of red giants and white dwarfs, and with a brief reference to neutron stars.

Stellar Magnetic Fields

2018
Abstract Recent developments in astrophysical spectropolarimetry have significantly expanded our understanding of stellar magnetism. Using modern instrumentation and data analysis methods it is becoming possible to detect and characterise surface magnetic fields not just for a few peculiar objects but for essentially all types of stars, ranging from ...

Stellar Magnetic Fields

1994
The study of the solar magnetic field was initiated in 1908, while that of stellar magnetic fields was only started in 1946. This is because stars are too far from us, and so much fainter and more difficult to observe than the Sun. Thanks to the efforts of astronomers through several generations, tremendous progress in both techniques of observation ...

Origin of stellar magnetic fields

Astrophysics and Space Science, 1972
It is pointed out that the magnetic field of a star is originated from dynamo action associated with the stellar evolution. The magnetic field of a star is related with how much nuclear energy is generated in its phase of evolution. From this we can explain why some stars possess a magnetic field high than that of the Sun.

Observing and Modelling Stellar Magnetic Fields

EAS Publications Series, 2009
We start by looking at some recent developments in field measurements in middle main sequence and pre-main sequence stars. Then we consider how other magnetic effects such as the Hanle effect and continuum polarisation may be used to detect fields in a variety of stellar environments such as the solar corona and white dwarf atmospheres.
