The Department of Astronomy at Stockholm University invites applications for one or more PhD-students in Astronomy directed towards Solar Physics. Reference number SU FV-3036-13.
The department consists of about 12 faculty professors/lecturers, another 15 senior and postdoctoral researchers, and over 20 PhD students. Stockholm is the capital of Sweden and has an international character. Most Stockholm researchers have an international background and English is commonly used both at the department and in daily life.
The hot and magnetised outer atmosphere of our closest star – the sun – is intensely studied because of its fascinating complexity, with bearing on astrophysics in general, and because of its influence on the Earth and our technological environment. A specific major goal for future large solar telescopes is to explain the dynamic solar chromosphere and how it couples to the underlying visible solar surface (the photosphere) and to the surrounding much hotter corona. The Institute for Solar Physics at Stockholm University operates the Swedish 1-m Solar Telescope (SST) on La Palma, which is one of the largest solar telescopes in the world. The SST is already a world-leading facility for studies of the chromosphere and its potential for such observations will be further enhanced with a new filter system dubbed CHROMIS in the near future. The group is presently expanding with new scientific and technical staff and has strong collaborations with other world-leading research groups in solar physics.
The hot and dynamic chromosphere is far more complicated to model and understand theoretically, and also to observe, than the photosphere. This project aims at clarifying the processes powering the chromosphere through one or several of the following approaches:
1) observations of the solar chromosphere with the SST, using existing and coming instrumentation,
2) comparison of SST data with synthetic spectra calculated from state-of-the-art theoretical simulations (developed by collaborators in Oslo),
3) developing and improving data reduction and analysis techniques to fully exploit the scientific potential and to further enhance the fidelity of the SST data and
4) connecting and interpreting SST data together with UV imaging and spectroscopic data recorded by space observatories. The thesis work will be tailored from these components in order to fit the student’s interests and abilities.
To be accepted for the PhD programme in astronomy, the applicant should have a University degree in Astronomy or Physics at the advanced level (e.g. a Masters). Stockholm University strives to be a workplace free from discrimination and gives equal opportunities for all.
