Abstract: We present a new seismic modelling and analysis of the CoRoT target HD52265. This star is the only know extrasolar-planet host star selected as a main target in the CoRoT seismology program, being observed continuously during five months. As a consequence, frequencies for l=0, 1 and 2 have been detected with an extremely good precision (Ballot et al. 2010, in preparation). We computed stellar evolutionary tracks using the TGEC, with four sets of different metallicities and Y values. We obtained their adiabatic oscillation frequencies using the PULSE code, and we compared them with the observable acoustic frequencies, keeping the models which best fit the observational echelle diagram for a further detailed analysis. This allow us to determine precise stellar parameters for this star, which is of great importance in the framework of planetary formation and evolution.
