About the Project
Filaments are a fundamental structure in the magnetised solar atmosphere, forming in regions of both intense and weak magnetic field. Observationally they are manifested by collections of relatively cool and dense plasma that is suspended against gravity in the million degree solar atmosphere.
Over the last couple of decades, descriptions of filaments have progressed from simplified 2.5 D models to highly dynamic structures where new areas of physics are now being applied to describe the observations. There are questions on, for example, the role of turbulence and instabilities in a dense, magnetised, partially ionised plasma.
This project will work on the physical mechanisms that lead to the formation of filaments. This involves understanding how a magnetised plasma evolves at the boundary between a gas pressure-dominated domain (in the lower solar atmosphere) and the domain where the magnetic pressure dominates (mid-solar atmosphere), and studying the evolution of the associated magnetic structures, and the partially ionised plasma that fills them. This project will make use of state-of-the-art multi-spacecraft observations, including the newly-launched Interface Region Imaging Spectrometer mission, to study the plasma parameters within the filament and in its environment, to understand the genesis of these structures.
UCL was one of the first universities in the world to become involved in making scientific observations in space. Since MSSL was established in 1966, we have participated in more than 35 satellite missions and over 200 rocket experiments. Our groups of research scientists and development engineers work together to ensure that the instruments we produce are as relevant and competitive as possible. The subsequent scientific interpretation of data benefits from the fundamental understanding of the instruments gained from in depth knowledge of their development and testing.
