Observational advances in helio- and astero-seismology have highlighted our poor understanding of the mechanisms of chemical mixing and angular momentum transport in the stably-stratified radiation zones of the Sun and other stars. This project will study various hydrodynamic or magnetohydrodynamic instabilities in stellar and planetary interiors that could contribute to mixing and angular momentum transport. These processes can modify the internal rotations, structures and evolutionary ages of stars, but they are commonly either neglected or modelled in an ad-hoc manner in current stellar models. This project will involve a combination of linear analysis and numerical simulations to understand the properties of one or more of these instabilities, and to determine their nonlinear behaviour. This may involve simulations on high-performance computing facilities, such as the Advanced Research Computing facility at Leeds. The ultimate goal is to understand the nonlinear outcome of these instabilities and to provide simple parameterisations of their mixing and angular momentum transport properties that can be incorporated in stellar models.<br /> <br /> The group in Leeds is one of the leading groups in the field of Astrophysical and Geophysical Fluid Dynamics (https://agfd.leeds.ac.uk), and is actively engaged in research&nbsp;on a wide range of topics including planetary and extrasolar planetary dynamics (the geodynamo, planetary dynamos, tidal interactions between planets and stars, planet formation), solar and stellar dynamics (solar and stellar dynamos, hydrodynamic and magnetohydrodynamic instabilities, turbulence), as well as galactic and extragalactic dynamics on the largest scales. Although this project does not have dedicated funding, all successful&nbsp;applicants without funding&nbsp;will be considered for both STFC funding, and for a&nbsp;fully-funded scholarship in an open competition across the entire&nbsp;School of Mathematics.
<p>The earliest start date for this project is 1 October 2021.</p>
<p>Formal applications for research degree study should be made online through the <a href="http://www.leeds.ac.uk/rsa/prospective_students/apply/I_want_to_apply.html">University's website</a>. Please state clearly in the research information section that the research degree you wish to be considered for is Hydrodynamic and magnetohydrodynamic instabilities in stellar and planetary interiors as well as <a href="https://eps.leeds.ac.uk/maths/staff/4006/dr-adrian-j-barker">Dr Adrian Barker</a> as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University's minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>
Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.
The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
