    Detecting individual gravity modes in the Sun: Chimera or reality?
    Over the past 15 years, our knowledge of the interior of the Sun has tremendously progressed by the use of helioseismic measurements. However, to go further in...

    Excitation of Solar Acoustic Modes
    The excitation of p-modes seems to be produced by turbulence in the convection zone (see, e.g., Kumar, 1997 and the references therein). Low-degree p-mode...
