New seismological results on the G0IV Bootis

Several attempts have been made to detect solar-like oscillations in the G0IV star Boo. We present here new observations on this star simultaneously conducted with two almost identical spectrographs: CORALIE, based on the 1.2-m Swiss telescope at the the ESO La Silla Observatory (Chile), and ELODIE, based on the 1.93-m telescope at the Observatoire de Haute Provence (France). The power spectrum of the high precision velocity time series clearly shows several identifiable peaks between 0.5 and 1.0 mHz with a maximal amplitude of about 75 cm s^-1. Preliminary impacts on modelisation of this subgiant star are discussed.
