    Asteroseismology or astroseismology is the study of oscillations in stars. Because a star's different oscillation modes are sensitive to different parts of the star, they inform astronomers about the internal structure of the star, which is otherwise not directly possible from overall properties like brightness and surface temperature. Prof. Leon Mestel has been an inspiration to many to study the role of magnetism in the Cosmos. To mark the occasion of his retin'ment from the University of Sussex after 43 years in astrophysics, several of his friends and former students decided to hold an advanced research workshop in hisMissing: Ap-stars.

White dwarf stars, compact objects with extremely high interior densities, are the most common end product in the evolution of stars. The authors review the history of their discovery, and of the realisation that their structure is determined by the physics of the degenerate electron gas.

There is good evidence that this driving mechanism is also valid in other classes of stars, such as the Mira stars.

Whether or not this happens at field strengths typical for Ap stars (– T) depends on the detailed fine-structure splittings of the terms involved. It is useful to recall that a field strength of 1 T corresponds to a splitting of gM cm −1, where g denotes the Landé factor and M is the magnetic quantum by: 8.
