Understanding the internal structure of pulsating Herbig Ae stars by the aim of an asteroseismological study will help to constrain the origin of the tremendous activity, winds and variability observed in this group of pre-main sequence stars.
The time analysis of the LSD profiles of HD104237 has revealed non-radial pulsations of low-degree. We present the mode identification corresponding to the detected frequencies. In addition, as we need to constrain a stellar atmosphere model in order to simulate the pulsations of HD104237, we have computed accurately its fundamental parameters (Teff, log g, abundances); we present the results of this study.
