Solar Physics

Heliophysics: Solar Atmosphere

Dr. Klimchuk’s research mostly concerns the structure, heating, stability, and dynamics of the outer solar atmosphere, including active regions, loops, prominences, flares, and coronal mass ejections. He places strong emphasis on the important link between theory and observation, using observations to both motivate and test his theoretical ideas. His theoretical work includes analytical modeling and numerical simulation of hydrodynamic and MHD systems. His observational work includes analysis and interpretation of imaging, spectroscopic, and polarimetric data in the soft X-ray, UV, visible, and radio wavebands.
