摘要：
Waves observed by high resolution telescopes in the solar corona are subject to a rapid damping which could be due to non-ideal effects and/or transversal inhomogeneities. The attenuation of modes is currently used to determine, e.g. the value and structure of coronal magnetic field, a fundamental parameter which cannot be measured directly. Here we study the damping of linear MHD modes propagating in a stratified plasma in the presence of thermal conduction. For the chosen particular equilibrium we show the importance of the transversal motion in the process of wave damping.
