Summary:

This book outlines the physics behind stellar oscillations and the information they encode about stellar structure, and summarizes the current state of the art in the field. It also describes commonly-used data reduction and analysis techniques and tools for asteroseismology, and discusses the uncertainties and limitations of both oscillation frequency measurements and the physical parameters derived from them. An introduction to some advanced topics, such as measurements of rotation and magnetic fields, is also included. The focus of the book is on the successful application, use, and physical interpretation of asteroseismology by nonspecialists in the field. It is aimed at professional and future professional astronomers at all levels from advanced undergraduate on up.
