About the Project

The corona, the most external layer of the solar atmosphere, is composed of coronal loops – magnetic field structures filled with ionised plasma at multi-million-degree temperatures on average. How these structures are heated constitutes a major astrophysical problem.

Coronal loops are permeated by magnetohydrodynamic (MHD) waves that can transport large amounts of energy. Wave-based heating mechanisms constitute therefore a major candidate to heat the corona. However, most, if not all, wave-based heating theories have only been successful in generating a “Quiet” corona. On the other hand, active regions, the most energy-demanding regions in the Sun, are thought to be mostly heated through magnetic reconnection, a fundamental mechanism of plasmas.

Recent observational and numerical results indicate that MHD waves can generate dynamic instabilities through which enhanced dissipation can be achieved, paving the way to a potential role in active region heating. Through this process magnetic reconnection can play a major role, thereby introducing a new paradigm in which waves and reconnection combine to efficiently heat the corona.

This project builds on the momentum gained through this recent development in wave research and aims at exploring this dual wave + reconnection scenario as a solution to coronal heating. The project includes numerical and observational parts. On the numerical side an advanced MHD code will be used that is able to properly capture wave and reconnection processes. On the observational side datasets from the state-of-the-art SDO and IRIS missions will be analysed to look for telltale signatures of the proposed heating mechanism, thereby constraining the theory.

We are primarily looking for applicants with a degree in Mathematics, Physics or Astrophysics. Previous experience of numerical modelling, observational data analysis and computer programming is desirable but not essential.

The principal supervisor for this project is Dr Patrick Antolin. The second supervisor will be Professor James McLaughlin.

Please note eligibility requirement:
