EDDINGTON AND THE INTERNAL CONSTITUTION OF THE STARS

摘要

Eddington will provide sets of frequencies of multi-mode oscillations for a very large number of stars of different masses, ages, compositions and angular velocities. This Will enable us. to infer their interior structure and dynamics, and hence to test our current understanding of stellar structure and to develop an empirically based theory of stellar evolution. Here I discuss some of the techniques available for inferring the structure of stars from a given set of frequencies. In particular, I demonstrate that, at least in solar type stars, the ratio of small to large separations subtracts off the the contribution of the surface layers yielding a diagnostic of the stellar interior alone.
