Abstract

Oscillatory phenomena observed in sunspot umbrae and penumbrae are reviewed and critically discussed. A natural interplay between the thermal atmospheric stratification and the ordered collimation imposed by the intense magnetic field leads naturally to the characteristic properties of the umbral chromospheric and photospheric oscillations and their interpretation as low- β ( β =8 πp / B 2 ) slow magneto-acoustic-gravity waves guided along the ambient magnetic field.
