Offer Description

The Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences (CAMK PAN) in Warsaw invites applications for a postdoctoral position in the project “Tracking Mass Flow in Binary Systems with Accreting White Dwarfs”, funded by the Polish National Science Centre (NCN) through a SONATA 20 grant (PI: Dr. Krystian Iłkiewicz ).

The project investigates the transfer and loss of mass and angular momentum in interacting binaries containing accreting white dwarfs, particularly cataclysmic variables and symbiotic stars. The research will focus on accretion-disc structure and variability, including disc tilts, precession, and instabilities, as well as the mechanisms responsible for winds and jets. We will also study extended structures, such as bow shocks and nova shells, to trace the history of mass loss from these systems and investigate how the ejected material interacts with the surrounding medium.

The research will make use of spectroscopic, photometric, and spatially resolved observations, together with theoretical modelling and interpretation. The successful candidate will work with existing observational datasets and collaborate with the project team on their analysis. There will also be opportunities to pursue related research and develop independent ideas within the scope of the project.

The successful candidate will conduct research related to the scientific objectives of the project, with a focus on accretion and mass-loss processes in interacting binary systems.

The main responsibilities will include:

• Conducting independent and collaborative research within the scope of the project;
• Analyzing and interpreting observational data and/or developing theoretical models;
• Publishing scientific results in peer-reviewed journals and presenting them at international conferences;
• Collaborating with the project team and contributing to its scientific activities.

Requirements

Research Field Astronomy » Astrophysics Education Level PhD or equivalent

Skills/Qualifications

Applicants must hold a PhD degree in astrophysics, astronomy, or a closely related field, obtained within 12 years by the time of appointment (this period may be extended in some cases) and fulfil the formal requirements of the NCN included in the Regulations on Awarding Funding for Research Tasks Funded by the National Science Centre as Regards Research Projects for the SONATA 20 competition (see Annex 2, 'Full-time remuneration for a post-doc type post' at https://www.ncn.gov.pl/sites/default/files/pliki/uchwaly-rady/2024/uchwala84_2024-zal1_ang.pdf ).

Applicants must also have a publication record appropriate to their career stage and a good working knowledge of English. Experience with scientific programming and data analysis would be an advantage.

We welcome candidates with backgrounds in observational or theoretical astrophysics. Relevant experience may include research on interacting binaries, accretion discs, stellar outflows, astronomical spectroscopy, time-domain photometry, spatially resolved observations, or theoretical and numerical modelling. The specific research activities can be tailored to the successful candidate's expertise and interests, and previous experience specifically with white dwarf binaries is not required.
