<h2 class="heading hide-accessible">Summary</h2>

Colliding Winds Binaries are stellar systems containing two (usually massive) stars each with a powerful stellar wind. In systems with O stars or Wolf-Rayet stars, the winds collide at very high speeds (1000-3000 km/s). The shocked gas radiates at X-ray energies and the shocks bounding the wind-wind collision region may accelerate particles to near light speed. The details of the particle acceleration and the resulting non-thermal emission from these systems remains poorly understood. This project will involve constructing new numerical models of the particle acceleration and emission, to compare against the latest observational data. This project is ideally suited to a candidate interested in conducting a computational project and who enjoys the challenge of coding.

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="https://eps.leeds.ac.uk/physics-research-degrees/doc/apply">University&#39;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is &ldquo;The Non-thermal Emission from Colliding Winds Binaries&rdquo; as well as <a href="https://eps.leeds.ac.uk/physics/staff/4126/dr-julian-pittard">Dr&nbsp;Julian Pittard</a> as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;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>

<h2 class="heading heading--sm">Entry requirements</h2>

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.

<h2 class="heading heading--sm">English language requirements</h2>

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.
