Inferring Energy Release from UV and Hard X-ray Observations of Flares

Advisors: Jiong Qiu and Angela DesJardins

Solar flares are spectacular energy release events in the Sun's atmosphere. It is understood that the energy to fuel flares is provided by the Sun's magnetic fields, most probably through a physical process called magnetic reconnection. Magnetic reconnection changes the way magnetic field lines connect to the Sun's surface, and the subsequent energy release is often manifested as heating along a multitude of newly formed magnetic flux tubes.

In this project, we will study the evolution of flare radiation signatures in magnetic tubes (loops) formed during reconnection, measure important parameters of magnetic reconnection and plasma evolution, and search for better understanding of the relationship between magnetic reconnection and energization of plasmas or particles in flux tubes. The student will analyze imaging and spectral observations of solar flares and magnetic fields by the satellites SDO and RHESSI. The student will learn about the Sun's atmosphere and magnetism. Experience with IDL or similar programming languages is desired though not required.
