Coronal oscillations as revealed by solar hard X-ray bursts
Abstract
During the 21st solar activity cycle, the HXRBS aboard SMM satellite and the HXM on HINOTORI spacecraft detected several thousand hard X-ray solar flares. Studies of the temporal properties of these events had revealed hundreds of examples of fast spikes with durations of less than 1 sec. Some of these observations were analyzed, and it was found that they have four common characteristics. Among these characteristics, quasi-periodic oscillations suggested the possibility of oscillations existing in the corona. The characteristics of the oscillations have been studied and their periods derived. The conditions of trapping the oscillations are also discussed.
