We study the sensitivity of the sound speed to relativistic corrections of the equation of state (EOS) in the standard solar model by means of a helioseismic forward analysis. We use the latest GOLF/SOHO data for , 1, 2, 3 modes to confirm that the inclusion of the relativistic corrections to the adiabatic exponent computed from both OPAL and MHD EOS leads to a more reliable theoretical modelling of the innermost layers of the Sun.
Key words: Sun: interior / Sun: oscillations / equation of state
