Abstract

The star HD 49933 has been observed by the mission CoRoT two times (for 60 and 137 days). Its spectrum shows a wealth of oscillation modes but was found difficult to analyse. In the following, we summarize why it was so, and then present a modeling of the star using seismic constraints and show the effect of the microscopic diffusion and of the overshoot in the modeling. We conclude that some convective overshoot from the core is needed while it is difficult to give a definitive conclusion concerning the effect of the microscopic diffusion on the modeling of HD 49933 (© 2010 WILEY-VCH Verlag GmbH & Co.
