    Abstract

    We present here a new result of ground-based asteroseismology obtained with the spectrograph HARPS. The exoplanets host star μ Arae was observed during an 8 nights campaign in order to understand the origin of the overmetallicity of planet-hosting stars. Thanks to very high precision Doppler measurements, we identified more than 20 p-modes in this star and compared it with different models. These results demonstrate the potential of ground-based Doppler asteroseismology and should be considered to be implemented in Dome C in the future in order to benefit of long and uninterrupted observations.
