Description

Many scientific theories have been proposed in the hopes of better understanding the coronal heating
problem. This project largely focuses on the theory that the Solar Corona is heated by Alfvén Wave
turbulence from solar coronal loops. These waves are thought to be propagated by motion at the foot
points of the coronal loops in which they originate. Our research contributes to this theory by focusing
specifically on the modeling of the Alfvén Wave turbulence in the coronal loops. We applied an idl
Coronal Modeling Software (Cms2, Asgari & Van Ballegooijen 2012), a graphical user interface (GUI)
based modeling system to two active regions observed by Hinode X-Ray Telescope (XRT) and the Solar
Dynamics Observatory (SDO). We modeled potential fields and based on these models, we investigated
wave turbulence and predicted that wave turbulence subsequently heats the Solar Corona. From this
research, we have learned that the atmosphere of the Sun is heated by Alfvén Wave turbulence to
temperatures of 1-2 MK.
