The current theory of the high‐degree solar f‐mode based on an adiabatic approximation is in contradiction with obser‐vations, since the f‐mode is visible in intensity oscillations of the Sun. As a possible solution we present an universal analytical treatment for a non‐adiabatic f‐mode. This non‐adiabatic theory provides the explanation of brightness oscilla‐tions due to the f‐mode. We find that the non‐adiabatic effects do not lead to a damping of the f‐mode since the dispersion relation is the same as in the adiabatic approximation (© 2012 WILEY‐VCH Verlag GmbH & Co.
