Chromospheric resonances above sunspots and potential seismological applications
T. Felipe, C. Kuckein, S. J. González Manrique +2
Oscillations in sunspot umbrae exhibit remarkable differences between the photosphere and chromosphere. We evaluate two competing scenarios proposed for explaining those observatio…

Signatures of sunspot oscillations and the case for chromospheric resonances
T. Felipe
Sunspots host a large variety of oscillatory phenomena, whose properties depend on the nature of the wave modes and the magnetic and thermodynamic structure of the spot. Umbral chr…

Numerical determination of the cutoff frequency in solar models
T. Felipe, C. R. Sangeetha
In stratified atmospheres, acoustic waves can only propagate if their frequency is above the cutoff value. Different theories provide different cutoff values. We developed an alter…
