Application Deadline: 23:59 CET, December 20, 2025
We invite applications for a postdoctoral research position within the ERC-funded program 2SStars — The Role of Binary-Stripped Stars: from Atomic Scales to Cosmic Dawn. The postdoc will join an active research team led by Dr. Ylva Götberg (www.ylvagotberg.com) at the Institute of Science and Technology Austria (ISTA). Our group uses both observational and computational approaches to investigate the physics of envelope-stripped stars. We explore how stripped stars can be used to understand binary interaction, gravitational wave and supernova transients, stellar interiors, and sources of ionizing radiation. We maintain strong international collaborations, and the postdoc will be encouraged to engage in these and expand their scientific network.
We particularly welcome applicants with expertise in hot star spectral modeling, binary population synthesis, nebular spectral modeling, or in designing and planning observational surveys. We seek candidates who are motivated by the science of envelope-stripped stars and eager to contribute creatively to the field of interacting binaries. We are committed to fostering an inclusive, supportive, and respectful research environment. We welcome applications from scientists of all backgrounds and identities, and we particularly encourage individuals from underrepresented or historically marginalized groups in astronomy to apply.
The expected starting date is September 2026 (flexible) and the position is for two years. The position includes funds available for necessary equipment purchases, travel resources, and publication costs. It is a fully paid employment contract with standard benefits, including health care, paid leave, and social security coverage.
Your profile
PhD in Astrophysics completed within the past 5 years.
