冕环共振阻尼振荡阻尼时间的标度
On the scaling of the damping time for resonantly damped oscillations in coronal loops
摘要：
对于TRACE观测到的日冕环中的振荡迅速衰减的机制，目前还没有完全一致的看法。有人建议，阻尼时间的观测值的变化作为相应的观测值的周期包含可能的阻尼机制的信息。这封信的目的是表明，对于共振吸收，这肯定不是这种情况下，除非详细的先验信息的个别回路是可用的。
英文摘要：
There is not as yet full agreement on the mechanism that causes the rapid damping of the oscillations observed by TRACE in coronal loops. It has been suggested that the variation of the observed values of the damping time as function of the corresponding observed values of the period contains information on the possible damping mechanism. The aim of this Letter is to show that, for resonant absorption, this is definitely not the case unless detailed a priori information on the individual loops is available.
