We present our results on asteroseismic modelling of the evolved Sun-like star beta Hydri. The solar-like power excess in the star's spectrum was detected in 2001. Recent observations made it possible to extract individual oscillation frequencies as well, which allowed us to perform a detailed modelling. We employed the Aarhus stellar evolution and adiabatic pulsation codes, ASTEC and ADIPLS, and corrected the theoretical frequencies for the near-surface offset caused by the improper modelling of the turbulent convection in the outer layers. We used up-to-date seismic and non-seismic observational constraints to find a model that represents beta Hydri best. Our best models reproduce the observed frequencies of the star, including the so-called 'mixed modes', which provide strong constraints on the age.
