Magnetic instabilities in solar filaments: models of twisting motionsand ejecta.
Abstract
Time sequences of two destabilized solar filaments were derived using a spectrograph operated in H alpha. The opposite directed velocities observed in the first filament are interpreted in terms of a twisted magnetic flux rope model. The sudden disappearance of the second filament corresponds to high velocity plasmoids confined in magnetic field lines and then ejected.
