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.

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 ...

On the interpretation of stellar magnetic fields
Vistas in Astronomy, 1955Abstract The present knowledge of stellar magnetic fields is reviewed. Their large variation with time in many stars presents a difficulty, the explanation of which in terms of mechanical oscillations is not satisfactory. In this paper a new attempt is made to examine under what conditions the measurements can be reconciled with the assumption of a ...

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, 1972It 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, 2009This and the following two chapters present a general introduction to the subject of observing magnetic fields in stars using spectropolarimetry. The three chapters will consider (1) the basic physics of the Zeeman and related effects, direct deductions about stellar magnetic fields that may be made where this effect is detected, and how such ...
