Prominence seismology View all abstracts by submitter

Given the difficulty in directly determining prominence physicalparametersfrom observations, prominence seismology stands as an alternativemethod toprobe the nature of these structures. We show recent examples of theapplication ofmagnetohydrodynamic (MHD) seismology techniques to infer physicalparameters inprominence plasmas. They are based on the application of inversiontechniques usingobserved periods, damping times, and plasma flow speeds of prominencethread oscillations.The contribution of Hinode to the subject has been of centralimportance.We show an example based on data obtained with Hinode's Solar OpticalTelescope.Observations show an active region limb prominence, composed by amyriad of thinhorizontal threads that flow following a path parallel to thephotosphere and displaysynchronous vertical oscillations. The coexistence of waves and flowscan be firmlyestablished. By making use of an interpretation based on transverseMHD kink oscillations,a seismological analysis of this event is performed. It is shown thatthe combinationof high quality Hinode observations andproper theoretical models allows flowsand waves to become two useful characteristics for our understanding ofthe nature ofsolar prominences.
