The coronal oscillations 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 1 sec. Some of these observations were analyzed, and it was found that they have four common characteristics. In particular, quasi-periodic oscillations suggested the possibility of existing oscillations in the corona. The characteristics of the oscillations were studied and their periods derived. The conditions of oscillation trapping are also discussed.
