| Abstract: |
Transverse and longitudinal waves in magnetic flux tubes are proposed as the explanation for the dynamics observed in network bright points. Impulsive excitation in the photosphere generates mainly transverse (kink) waves. They become nonlinear in the chromosphere and then couple to longitudinal flux tube waves, which dissipate in shocks. The oscillation period observed in the chromospheric network is interpreted as the cutoff period of transverse flux tube waves. |
