Postdoctoral positions on the study of evolved stars
Ref REF 2023-0568
Information about the division and the department
Research at the Department of Space, Earth and Environment (SEE) addresses fundamental scientific topics. On the one hand, we focus on basic science related to the origins of universe, of our planet and of life. On the other, we observe what is happening on Earth today and develop methods, tools and models that enable us to look towards the future and find solutions to global challenges about resources, energy supply and environmental impact. The research in the division of Astronomy and Plasma Physics (AoP) covers a wide range of topics, including evolved stars, interstellar medium, astrochemistry, star and planet formation, exoplanets, observational cosmology, galaxy formation and evolution and galaxy clusters. The activities of AoP are primarily situated at the main Johanneberg Campus with further pressence at the Onsala Space Observatory (OSO), which is the Swedish national facility for Radio Astronomy. The observatory operates telescopes in Sweden, shares in the APEX telescope in Chile, and hosts the Nordic ALMA Regional Center (ARC).
Applications are invited for up to three postdoctoral positions, two in the area of low-mass evolved stars on the asymptotic giant branch (AGB) and one in the area of high-mass evolved stars in the red supergiant (RSG) phase. The research for one position will be within our project about probing the extended atmospheres of AGB stars, for the second position in the investigation of the wind-Interstellar Medium (ISM) interaction regions around AGB stars, and for the third position in the investigation of molecular emission and the mass-loss process around RSGs. The postdoctoral positions will be for 2-years with a possible 1 year extension dependent on the availability of funding. The succesful applicants will work with Prof. Wouter Vlemmings, Dr. Theo Khouri, Dr. Matthias Maercker, Dr. Elvire De Beck, as well as other members of the evolved star research group in AoP.
The three positions will address three different projects:
1) For the first position, the major responsibility as postdoc is to work with several large data-sets, obtained with ALMA, on the continuum and molecular line emission originating from the extended atmospheres of AGB stars. These new data have been (and are being) acquired in 2023. The work will include multi-dimensional radiative transfer.
2) The second position focuses on the interaction of the stellar winds with the ISM. The major responsibility as postdoc in this project is to develop hydrodynamical models of the wind-ISM interaction regions, providing the physical conditions in these regions. The models will be used to compare to observations in the infrared to determine the effect on the properties of dust grains released into the ISM.
3) For the third position, the major responsibility as postdoc will be to analyse and develop radiative-transfer models for multiple recent data sets, including both single-dish and interferometric measurements of molecular emission from RSG outflows.
The succesfull applicants will also have the opportunity to collaborate in other projects from members of the evolved stars research group at Chalmers. Furthermore, there is a strong synergy with the work within the large interdiciplinary research project "The Origin and Fate of Dust in the Universe", which is a collaboration between astronomers at Chalmers and theoretical physical chemists at Gothenburg University. It will be possible to join this collaboration as an affiliate member. The positions might also include opportunities for small fractions of time teaching on undergraduate and master's levels as well as supervising master's and/or Ph.D. students. The positions are meritorious for future research duties within academia as well as industry/the public sector.
To qualify for these postdoc positions, you must have a Ph.D. in astronomy or a relevant field and a demonstrated potential for research. Preference is given to candidates with previous experience with interferometric observations, radiative transfer, hydrodynamical modelling and/or with evolved stars.
The position requires sound verbal and written communication skills in English.
Full-time temporary employment. The postdoctoral positions will be for 2-years with a possible 1 year extension dependent on the availability of funding.
Chalmers offers a cultivating and inspiring working environment in the coastal city of Gothenburg.
