About this product
- DescriptionThis mograph attempts to provide a systematic and consistent survey of the fundamentals of the theory of free, linear, isentropic oscillations in spherically symmetric, gaseous equilibrium stars, whose structure is affected neither by axial rotation, r by the tidal action of a companion, r by a magnetic eld. Three parts can be distinguished. The rst part, consisting of Chaps.1-8, covers the basic concepts and equations, the distinction between spheroidal and toroidal rmal modes, the solution of Poisson's differential equation for the perturbation of the gravitational potential, and Hamilton's variational principle. The second part, consisting of Chaps.9-13,is devotedto the possible existenceof waves propagating in the radial direction, the origin and classi cation of rmal modes, the comple- ness of the rmal modes, and the relation between the local stability with respect to convection and the global stability of a star. In the third part, Chaps.14-18 c- tain asymptoticrepresentationsof rmalmodes. Chapter 19 deals with slow period changes in rapidly evolving pulsating stars. The theory is developed within the framework of the Newtonian theory of gr- itation and the hydrodynamics of compressible uids. It is described in its present status, with inclusion of open questions. We give preference to the use of the adjective isentropic above that of the adjective adiabatic , since, from a thermodynamic point of view, these stellar - cillations are described as reversible adiabatic processes and thus as processes that take place at constant entropy.
- Author BiographyPaul Smeyers is professor em. in astrophysics at the Institute of Astronomy of the Catholic University Leuven, Belgium. Tim Van Hoolst is part-time professor at the same institute and senior research scientist at the Royal Observatory of Belgium. Both are long-time teachers and researcers in the field of stellar oscillations.
