title = "Low-frequency magneto-acoustic waves in the solar chromosphere",
abstract = "We show that inclined magnetic field lines at the boundaries of large-scale convective cells (supergranules) provide {"}portals{"} through which low-frequency (< 5 mHz) magneto-acoustic waves can propagate into the solar chromosphere. The energy flux carried by these waves at a height of 400 km above the solar surface, is found to be a factor of four greater than that carried by the high-frequency (> 5 mHz) acoustic waves, which are believed to provide the dominant source of wave heating of the chromosphere. This result opens up the possibility that low-frequency magneto-acoustic waves provide a significant source of energy for balancing the radiative losses of the ambient solar chromosphere.",
