Postdoctoral Fellow in Determination of Solar Chromospheric Magnetic Fields with Applications to Space Weather

Ref. No. SU FV-3123-18

at the Department of Astronomy. Closing date: 31 October 2018.

The Institute for Solar Physics at the Department of Astronomy, Stockholm University invites applications for a postdoc position. The successful candidate will work on Determination of solar chromospheric magnetic fields with applications to space weather predictions.

Project description
This work is part of a large project titled Research to develop, verify and quality control the infrastructure for warnings of extreme and dangerous solar storms which is funded by the Swedish Civil Contingencies Agency. The project is a collaboration between the Institute for Solar Physics in Stockholm, the Institute for Space Physics in Uppsala, and the Swedish Defence Research Agency.

Main responsibilities
The candidate will work mainly with Dr. Sanja Danilovic, Dr. Jaime de la Cruz Rodriguez and Dr. Jorrit Leenaarts on the further development and application of an inversion code that can reliably invert spectropolarimetric data from solar chromospheric lines such as Ca II 8542 and He I 10830. The ultimate goal is to develop a user-friendly inversion code that can be used to derive force-free chromospheric boundary conditions for both global and local magnetic field extrapolations or drive magneto-frictional models. These can be used as input to space weather applications such as forecasting the evolution of coronal mass ejections.

Qualification requirements
Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country.

Assessment criteria
The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.
