[ 1 ] - برانگیختگی و میرایی نوسانات عرضی در حلقه‌های تاج توسط پدیده ویک
Transversal oscillation of coronal loops that are interpreted as signatures of magneto hydrodynamics (MHD) waves are observed frequently in active region corona loops. The amplitude of this oscillation has been found to be strongly attenuated. The damping of transverse oscillation may be produced by the dissipation mechanism and the wake of the traveling disturbance. The damping of transversal ...
[ 2 ] - زمان میرایی نوسانات عرضی کینک مشاهده شده در حلقه های تاج نواحی فعال با استفاده از تلسکوپ ای آی ای نصب شده بر اس دی او
A coronal loop can be oscillated in various directions. A basic type of coronal loop oscillation is called transverse oscillation that can be caused by different factors, such as nearby active regions and flares. The damping of transverse oscillation may be produced by the dissipation mechanism or the wake of the traveling disturbance. The aim of this paper is to estimate the damping time of tr...
[ 3 ] - طول میرایی امواج مغناطوآکوستیک آرام مشاهده شده در حلقه‌های تاج با استفاده ازتلسکوپ اس- دی- او
Slow magneto-acoustic waves are often observed in polar plumes and active region fan loops. The observed periodicities of these waves are in the range of 1- 40 minutes. Mainly, the ratio of damping time to the oscillation period is less than 2 (equal to the ratio damping length to the wave length), which corresponds to the strong damping regime. In general, slow magneto-acoustic waves can be da...
