Abstract
We present HARPS spectroscopy of μ Arae (HD 160691) performed for studying the origin of the metallicity excess in this planet-hosting stars. The asteroseismologic campaign led to the previously reported discovery of a 14 earth mass planetary companion (Santos et al. 2004b, A&A, 426, L19). The present analysis reinforces this interpretation by excluding other possible processes for explaining the observed Doppler variation and leads to the identification of up to 43 p-mode oscillations with l = 0–3, frequencies in the range 1.3–2.5 mHz and amplitudes in the range 10–40 cm s-1.Keywords
