Abstract: | Prominence seismology is a rapidly developing topic which seeks to infer the internal structure and properties of solar prominences
from the study of its oscillations. Two-dimensional high-resolution observations suggest that filaments can be considered
as made by small scale fibrils, having a cool region, stacked one after another in the vertical and horizontal directions.
An extense observational background about oscillations in filaments has been gathered during the last 20 years and these observations
point out that fibrils or groups of fibrils can oscillate independently. From the theoretical point of view, small amplitude
oscillations in single and multifibril configurations have been studied as a first step to explain observational features. |
