Abstract

For the radial pulsations treated in the foregoing sections, the velocity has only one non-vanishing component, v r , which depends only on r. This is so specialized a motion that one might wonder why a star should prefer to oscillate this way at all. In fact it is easier to imagine the occurrence of perturbations that are not spherically symmetric, for example those connected with turbulent motions or local temperature fluctuations. They can lead to non-radial oscillations. We will limit ourselves to indicating a few properties of the simplest case: small (linear), adiabatic, poloidal-mode oscillations.
