Solar Atmospheric Magnetoseismology is the study of the Sun’s atmosphere by exploiting Magnetohydrodynamic waves to probe the local plasma environment, inverting measured wave properties to obtain difficult to measure plasma parameters. Inspired by geo-seismology and helioseismology, the field started in the late 1980’s from theoretical foundations. It was only in the late 1990’s that, with the launch of ESA’s Solar and Heliospheric Observatory (SOHO) & NASA’s Transition Region and Coronal Explorer (TRACE), the first observations of MHD waves in the corona were made. Much progress was made in probing the Sun’s corona, although, the observations were few and far between. This was changed with the commissioning of the Coronal Multichannel Polarimeter (CoMP) in 2007 and the launch of JAXA’s Hinode mission, which found evidence for ubiquitous MHD waves in the corona and chromosphere. The past decade has led to numerous studies of these waves, however, it has become clear that the theoretical assumptions underlying the magneto seismological inversion techniques are, in general. not satisfied. With access to a wealth of MHD wave observations in the Sun’s atmosphere and the promise of improved instrumentation in the near future, it’s time to revisit the basics and prepare!
The following pages provide information for an ISSI team meeting that will be discussing the subject – ‘Towards a Dynamic Solar Atmospheric Magnetoseismology’. Here you will find details of the team members, our objectives and details of the meetings.
Our first meeting took place on the 27th March 2017.
