Abstract

HD 49330 (B0.5IVe) has been observed with CoRoT during the LRA1 run and presented an outburst of moderate amplitude (0.03 mag). The analysis of its light curve revealed many frequencies in the Fourier spectrum typical of p and g pulsation modes with amplitude variations along the run closely correlated to the outburst. The simultaneous spectroscopic observations allowed us to identify some p and g modes. Using these results, we performed a preliminary seismic modeling of the Be star HD 49330 taking into account its rapid rotation.
