Fig. 5


Period, damping time, and damping ratio as a function of the density in the evacuated part of the tube for prominence threads with ρf/ρc = 200, a = 1, Rm = 106, lz = a, and l/a = 0.2 and three values of the length of the thread. The main plots are for ρc ≤ ρev ≤ ρf, while the inset plots correspond to the range 0.1ρc ≤ ρev ≤ ρc. Times are shown in units of the internal filament Alfvén crossing time, τAf = a/vAf. All computations have been performed in a two-dimensional grid with Nr = 401 and Nz = 51 points, with 250 grid-points in the resonant layer. Lengths are normalised to a = 1 and L = 50a.
