SP5: Waves in the solar atmosphere

Session Organisers:

M. Mathioudakis (University of Belfast, UK), Richard J Morton (University of Sheffield, UK)


Over the last few years, magnetohydrodynamic (MHD) waves and oscillations have been observed to be continuous and ubiquitous in all the different layers of the solar atmosphere with both space-based missions (e.g. SOHO, TRACE, STEREO, Hinode & SDO) and ground-based facilities (e.g. ROSA & COMP/DST, CRISP/SST, TESOS/VTT, GONG/NSO etc). The generated waves are believed to play a hugely important and influential role in determining the behaviour of the Sun's highly structured and dynamic atmosphere from the solar surface up to the corona, even determining Space Weather in the interplanetary space.

The aim of this session is to discuss recent advancements, challenges and future directions in the theory, simulation and observation of wave phenomena from the interior to the outer layers of the solar atmosphere.
