Damping of Fast Magnetohydrodynamic Oscillations in Quiescent Filament Threads
High-resolution observations provide evidence of the existence of small-amplitude transverse oscillations in solar filament fine structures. These oscillations are believed to represent fast magnetohydrodynamic (MHD) waves and the disturbances are seen to be damped in short timescales of the order of 1 to 4 periods. We propose that, due to the highly inhomogeneous nature of the filament plasma ...
متن کاملCoupled Dynamics and Quiescent Phases
We analyze diffusively coupled dynamical systems, which are constructed from two dynamical systems in continuous time by switching between the two dynamics. If one of the vector fields is zero we call it a quiescent phase. We present a detailed analysis of coupled systems and of systems with quiescent phase and we prove results on scaling limits, singular perturbations, attractors, gradient fie...
متن کاملSTUDY OF RIBBON SEPARATION OF A FLARE ASSOCIATED WITH A QUIESCENT FILAMENT ERUPTION HaiminWang,
In this paper, we present a detailed study of a two-ribbon flare in the plage region observed by Kanzelhohe Solar Observatory (KSO), which is one of the stations in our global H network. We select this event due to its very clear filament eruption, two-ribbon separation, and association with a fast coronal mass ejection (CME). We study the separation between the two ribbons seen in H as a funct...
متن کاملA Theoretical Approach to Actin Filament Dynamics
Dynamic control of the actin network in eukaryotic cells plays an essential role in their movement, but to date our understanding of how the network properties are controlled in space and time is still rudimentary. For example, how the cell maintains the pools of monomeric actin needed for a rapid response to signals, how the filament length distribution is controlled, and how the actin network...
متن کاملPhotospheric magnetic field changes associated with the activations of a quiescent filament
The disturbances of a quiescent filament and associated evolution of photospheric magnetic field were examined. The whole filament was broken into three sections by two filament breaks. In different sections, three distinct disturbances took place: two major ones with similar characteristics and a transient one. The presence of filament twist and the highly sheared filament magnetic field were ...
