Session Title New Views on MHD Waves in Chromospheric and Coronal Magnetic Structures
Main Convener Dr. Mario Bisi (Science & Technology Facilities Council - Rutherford Appleton Laboratory, United Kingdom)
Co-convener(s) Dr. Nanan Balan (Nagoya University, Japan)
Session Description The advent of high-resolution ground- and space-based observatories now reveal
the ubiquitous presence of MHD waves in the various magnetic structures of the solar
chromosphere and corona. The in-situ observations of these waves in such magnetic
waveguides provide a tool to diagnose their local plasma conditions using the principle
of solar magneto-seismology (SMS). Exploring the plasma properties (e.g. density,
temperature, magnetic field) by means of MHD waves, they may provide insight into the
local dynamical conditions as well as energetics bringing us closer to fully understand the
outstanding problem of chromosphere/coronal heating, and also provide some insight how
the plasma flows/dynamics contribute to the nascent wind formation.

The Interface Region Imaging Spectrometer (IRIS) now provide new views of small-scale
chromospheric structures, and the evolved MHD waves therein. Studying chromospheric physics is one of the most significant steps in revealing the heating of the solar atmosphere, IRIS, now, is having novel views on MHD waves in the complex magnetic environment of the chromosphere.

It is proposed to organize a one-day session with pioneering experts of MHD waves & oscillations in Solar Physics (both theorist and observers), and in proportionate strength, with the young researchers and students to discuss the latest discoveries/developments of MHD waves in the solar atmosphere, and their potential implications. Further, future plans and collaborations will be sought on this forum to basically carry forward the gained knowledge to the next stage, and to widen the research cooperation in understanding the wave phenomena in the magnetized solar atmosphere within the Solar Physics
community.
