Magnetic flux emergence on the Sun.

About the Project

A key open question in solar physics is how magnetic fields emerge from the solar interior to the surface of the Sun, to form sunspots and active regions. A PhD project on this topic will involve the running and interpretation of magnet-hydrodynamic simulations to understand the nature of the magnetic flux emergence process and the associated onset/triggering of dynamic events (jets, eruptions, flares), both on small scales and on a larger global scale (references). This work requires the use and development of the existing numerical codes. The results from the simulations will be applied to interpret past, recent and future observations by various solar missions, and to test predictive capabilities of these simulations.

H2020-ERC (synergy grant) funding is available for a PhD project on this subject to start immediately, subject to eligibility.

This project will strongly complement and benefit from the research, which is conducted by the other 4 European institutions involved in the ERC synergy grant ( ) running from 2019-2015.

Funding Notes

H2020-ERC (synergy grant) funding is available for a PhD project on this subject, subject to eligibility (overseas tuition fees are not covered).

Applicants should have (or be about to complete) an undergraduate degree and/or taught postgraduate degree in (applied) mathematics or (theoretical) physics. Past experience shows that successful applicants usually have a very good first class degree (or equivalent). Applicants with computational experience are encouraged to apply. In addition, the applicants must have excellent communication, planning and team working skills.
