| Abstract: |
Oscillating stars occupying various parts of the H-R diagram differ in types of excited modes. In this review I distinguish four types of oscillations encountered in stars. These are: pure g-modes; mixed modes; high amplitude radial modes; and high-order p-modes. I discuss separately how the frequency data of each of these types are being used to obtain constraints on uncertain aspects of stellar physics. The most troubling uncertainties concern convection, its efficiency in energy transport, and the extent of element mixing beyond boundaries of the unstable regions. There are uncertainties in the description of angular momentum transport and various coefficient from microscopic physics. I also give a brief survey of unsolved problems in stellar oscillation theory awaiting progress in numerical simulations. |
