Abstract
We performed asteroseismic modelling of two solar-like subgiant stars using the observed individual frequencies and the atmospheric constraints ([Fe/H], Teff and logg) determined through spectroscopy. From a classical analysis, these two stars have very similar parameters (especially Teff and logg, but seismology allows us to determine their own global parameters and compare their predicted internal structures through fitting their individual frequencies. We also check if there is sufficient information provided through the acoustic glitches that can be used to discriminate between different stellar models.
