Modeling, observing and understanding flows and magnetic fields in the Earth's core and in the Sun


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store

If you have been contacted by this company please contact us as soon as possible.

Workshop theme:

Like many other stars and planets, the Earth and the Sun possess magnetic fields built by dynamo action. Unlike the magnetism of most other astrophysical objects, though, the Solar and terrestrial fields have been closely studied for generations, yielding a wide variety of observational constraints that continue to challenge theory and defy prediction.  Both analytical theory and numerical simulations have cumulatively yielded significant insight into how both objects build their magnetism, but a comprehensive understanding of this process has remained elusive.  

This meeting will aim to scrutinise and assess the results of such modelling efforts by comparison to the vast and ongoing array of observations of both the Earth and the Sun.  By studying the detailed constraints provided by these two objects, we aim to gain insight into the dynamo process in stars and planets more generally. One aim of the meeting will be to examine the complementary constraints provided by direct numerical simulation and by other methods — e.g., reduced systems of equations valid in an appropriate asymptotic limit.  We may aim to identify future targets for numerical simulation, seeking both to identify tractable problems that could test mathematical dynamo theories, and to determine routes by which numerical models could be made more realistic. Another topic of interest is the role played by waves (influenced by rotation, magnetism, and buoyancy) in the dynamo process, and the prospects for using any observable signatures of such waves to infer information.  We will also discuss methods (including data assimilation techniques) that aim to turn dynamo models intro predictive tools, and assess the ultimate limits of such predictability.
