Globular clusters in the Milky Way are dense, old, stellar clusters thought to comprise at least two stellar populations. The formation and/or evolutionary path between these populations is still to be understood but is evident in anti-correlations in elements that are the product of the CNO cycle. High quality spectroscopic samples at high resolution are essential to fully trace the chemical signatures of these populations. These can be used to explore if there are any evolutionary connections using statistical techniques relevant for clustering and evolutionary studies. The project provides the opportunity to work with high resolution stellar spectroscopy datasets from large scale surveys such as the Gaia-ESO Survey and from the University of Canterbury Ōtehīwai Mt John Observatory. The stellar parameters and chemical abundances will be investigated for population signatures. This will require use of statistical methods to explore the datasets. A stipend of New Zealand Dollars $32,000 p.a. plus fees for 3 years is available, as well as funding for participation in international conferences. It is expected that the candidate will proactively search for additional funding support to e.g. travel to conferences, research internships. Candidates interested in gaining complementary outreach and teaching experience are welcome to apply. Prospective student must meet PhD enrolment requirements by the University of Canterbury.
Supervisors
Primary Supervisor: Dr C. Clare Worley
Key qualifications and skills
A strong background in stellar astrophysics and spectroscopic analysis with an interest in high-resolution stellar spectroscopy, stellar evolution, and stellar parameter and chemical abundance determination. Experience in carrying out observations in high resolution spectroscopy and in spectroscopic data reduction are highly valuable. Excellent team-working skills are required - successful candidates are expected to be comfortable working both independently and in a collaborative environment with other project postgraduate students. Good time management and communication (both written reports and verbal) skills are also required. Prior postgraduate experience is required either in an MSc degree, first class or second class division II honours degree, or equivalent in Astronomy, Physics or related subject.
Does the project come with funding
