We present here the detailled modelling of the exoplanet-host star μ Arae, which is known to harbour a four-planets system. This star presents a metallicity excess compared to stars without detected planets. Asteroseismology can help determining precisely its internal structure, μ Arae was observed with the HARPS spectrograph at La Silla Observatory in June 2004, and 43 p-modes were identified. Using the external parameters provided by spectroscopy and the seismic constraints, we computed new stellar models, in a wider range and more precisely than [1], with various assumptions (overmetallic or accretion scenario, overshooting or not, Y enriched with metals or Y fixed to its solar value). We tried to find which ones give the best fit to the observations.
