State and future of coronal seismology — •Erwin Verwichte — University of Warwick, UK

Coronal seismology is a technique that uses measurements of waves in the corona of the Sun to probe the structures they travel through and to provide information that would otherwise be difficult to measure directly. The past decade of solar observation has revealed the ubiquitous nature of waves of all types present in the corona. As a result, great strides have been made in wave modelling using theories that have relevance for coronal heating and solar wind acceleration. I will review the current state of coronal wave studies and highlights results using observations from the Solar Dynamics Observatory and discuss the limits and opportunities for coronal wave physics. I will show that seismology should not be seen in isolation but together with magnetic extrapolation and spectroscopy efforts.
