Solar Magneto-Seismology: How close we are to solve one of the great problems of modern astrophysics?

Abstract

Recent satellite (SOHO, TRACE, STEREO, Hinode, SDO) and ground-based (DST/ROSA, IBIS, CoMP, STT/CRISP) observations have provided plenty of clear evidence of waves present in the solar atmosphere. The detection and analysis of these waves allows us to perform sub-resolution solar magneto-seismology (SMS) of the solar plasma. First I will outline the latest developments in solar MHD wave theory focussing on linear waves and the SMS tool.

Next, I will concentrate on the role of the various MHD waves, and will discuss the latest status on detecting them. Within the framework of MHD I will discuss their photospheric origin and generation mechanism. I will embark on showing how MHD waves sail throughout the chromosphere, transition region or even into the corona. 

Finally, I will make a case how the new observational data on MHD waves can be used towards solving the solar heating enigma.

Bio

Professor Robertus von Fáy-Siebenbürgen, also publishing under Erdélyi, heads the Solar Physics and Space Plasmas Research Centre in Sheffield, UK. Amongst other international roles, he is a member of the Executive Committee of the World Institute for Space Environment Research (WISER), panel member of PPARC Solar Orbiter Committee and Chair of the UK Solar Physics Community. He has made a leading contribution to the theoretical and observational study of linear and non-linear resonant magnetohydrodynamic (MHD) wave heating under solar atmospheric conditions. The work is relevant to researchers in high performance computing and those with interests in astrophysics, astronomy and space physics.
