  • 摘要:Photospheric waves in sunspots moving radially outward at speeds faster than the characteristic wave velocities have been recently detected. It has been suggested that they are the visual pattern of p-modes excited around 5 Mm beneath the sunspot’s surface. Using numerical simulations, we performed a parametric study of the waves observed at the photosphere and higher layers that were produced by sources located at different depths beneath the sunspot’s surface. The observational measurements are consistent with waves driven between approximately 1 Mm and 5 Mm below the sunspot’s surface.
