Coronal Loop Oscillations: Overview of Recent Results In Observations
Abstract
Recent observations by high-resolution space imaging telescopes have revealed a variety of coronal oscillation modes. In addition to observations of transverse kinkmode oscillations and propagating longitudinal waves in coronal loops detected by TRACE and SOHO/EIT, more recently, SOHO/SUMER discovered standing slow magnetoacoustic waves in hot coronal loops through Doppler shift measurements. We present overviews and comparisons of physical properties of different oscillation modes, and discussions of their triggers and dissipation mechanisms. The application of coronal seismology models constrains the coronal magnetic field strength and dissipation efficiency, vital parameters for our understanding of coronal energy transport mechanisms.
