Descripción
We present a method for the analysis of latitude distribution associated
with temperature and/or velocity perturbations of the stellar surface
due to non-radial pulsation (NRP) modes in rapidly rotating B stars. The
technique is applied together with Fourier Doppler Imaging (FDI) to high
resolution and high signal-to-noise ratio spectroscopic observations of
ɛ Per. The main advantage of this approach is that it decomposed
complex multi-periodic line profile variations into single components,
allowing the detailed analysis of each mode seperately. We study the
10.6-d-1 frequency that is particularly important for modal
analysis of non-radial pulsations in the star.
