Relativistic effects in the solar EOS
Abstract
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 = 0,1,2,3 modes to confirm that the inclusion of the relativistic corrections to the adiabatic exponent Γ1 computed from both OPAL and MHD EOS leads to a more reliable theoretical modelling of the innermost layers of the Sun.
