Observational studies of massive star formation


Coronavirus information for applicants and offer holders

We hope that by the time you’re ready to start your studies with us the situation with COVID-19 will have eased. However, please be aware, we will continue to review our courses and other elements of the student experience in response to COVID-19 and we may need to adapt our provision to ensure students remain safe. For the most up-to-date information on COVID-19, regularly visit our website, which we will continue to update as the situation changes

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

Leeds is one of the leading institutes in the in the observational study of massive star formation. We have specific interests in the near infrared, radio and mm properties, since these can probe the disc around the young star, as well as the jets and winds it generates. These markers help us to understand how massive stars form.

<h2 class="heading hide-accessible">Full description</h2>

<p>Two specific project areas are offered.</p> <p>The first utilises a combination of near infrared spectroscopy and radio continuum imaging.&nbsp; Data in hand include studies of the molecular absorption lines, which give the structure of the cool gas very near to the star, and hydrogen and helium emission lines, which gives the velocity structure of any jet or wind present.&nbsp; These will be compared with the expected results from existing models for young protostars of this mass.&nbsp; Radio continuum data allows us to study the jets.&nbsp; Radio is valuable since it is not effected by the dust that obscures these regions, so allows a much fuller sample to be studied.&nbsp; Continuum data allows us to quantify the mass loss rate from the star.&nbsp; The high spatial resolution offered by facilities such as the VLA permit the evolution of the jets to be studied which further constrains the emission mechanism present.</p> <p>The second project seeks to develop modern statistical techniques in order to characterise star formation regions.&nbsp; This is an extension of the work this group has carried out as part of our EU funded StarFormMapper project.&nbsp; The aim is to enhance existing techniques, whether drawn from astronomy or other fields such as geostatistics, as well as to develop new methods.&nbsp; The data to be studied will include those from the Gaia satellite, as well as other space based and ground based surveys, and will aim to determine which methods are the best at comparing what we see in real life with the outputs from simulations.</p>

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

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="">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;Observational studies of massive star formation&rdquo; as well as <a href="">Dr Stuart Lumsden</a>&nbsp;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.
