Main lessons from GOLF/SOHO instrument on dynamics of the radiative zone, fundamental physics and energetics
Abstract
The GOLF instrument aboard SoHO has reached its main objectives and reveals its power to constrain fundamental physics, energetics and dynamics of the radiative zone. The Standard Solar Model (SSM) is no more sufficient to interpret all the seismic observations of the solar radiative zone. We confront the main results of GOLF to models beyond the SSM assumptions. We discuss the missing processes and quantify some of them to build a more realistic view of our star. Present works on GOLF instrument are now turned on its capability to follow the solar activity and on a tentative to detect more gravity modes. All the results are useful for solar-like stars observed by COROT and KEPLER.
