About article:
High-resolution spectroscopic time-series of rapidly oscillating Ap stars
show evidence that standing and running waves can co-exist in their
atmospheric layers. In order to understand these observations we
have carried out a theoretical analysis of the pulsations in the outermost
layers of these stars. By using the analytical solutions for the velocity
components appropriate to the model considered we derive an estimate of the
velocity component parallel to the line of sight averaged over the visible
stellar disk, and derive the relative amplitude and the phase for our model
as a function of height in the atmosphere.
