Oscillations in coronal structures: Recent Progress
Abstract
The presence of small-amplitude oscillations in prominences/filaments is well-known from long time ago. These oscillations, whose exciters are still unknown, seem to be of local nature and are interpreted in terms of magnetohydrodynamic (MHD) waves. During last years, observational evidence about the damping of these oscillations has grown and the mechanisms able to damp these oscillations have been the subject of intense theoretical modelling. Here, we summarize some of the theoretical results obtained about the time damping of small-amplitude oscillations in prominence/corona medium.
