PublicaciónDetecting 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...

PublicaciónDetection and temporal coherence of p-modes below 1.4 mHz
Data collected recently by the helioseismic experiments aboard the SOHO spacecraft have allowed the detection of low degree p-modes with increasingly lower...

PublicaciónExcitation 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...
