Solar B as a tool for coronal wave studies

V.M. Nakariakov

Direct observational evidence of the wave and oscillatory activity of the = solar corona is abundant in all observational bands and includes recent = discoveries of propagating compressible waves in polar plumes and near = loop footpoints, flare-generated transverse oscillations of loops, and = longitudinal and sausage standing oscillations within loops. These = phenomena are confidently interpreted in terms of magnetohydrodynamic = (MHD) waves. This observational breakthrough gave rise to the rapid = development of a new method for the remote diagnostics of the coronal = plasma, MHD coronal seismology, allowing for estimation of the absolute = value of the magnetic field in coronal loops, Alfv\'en speeds, transport = coefficients, fine structuring, heating function and other important = coronal parameters. EIS and XRT instruments provide us with an excellent = tool for the further development of coronal wave studies and especially = flare generated oscillations and waves. We present the recent findings, theoretical estimations of the observabilit= y of different MHD modes with Solar B instruments, theory-based observation= al and data analysis strategies and some ideas about the utilisation of = the results for coronal seismology. The expected results are of particular = interest for the revealing of coronal heating mechanisms.
