The envisioned research will start from assembled literature samples of observed massive close binaries with one or more pulsating components. The aim is to use their measured asteroseismic properties, such as internal rotation and magnetic fields, to develop new modelling tools and interpret observed tidal effects. The tools should be able to compute the excitation and damping of (nonlinear) tides throughout the evolution of multiple systems, as well as to model tidal effects in observed binaries.

An observation-driven modelling approach is envisioned, with the aim to calibrate tidal dissipation in binary evolution models of interacting dynamical rotating stars.

Applicants with a PhD degree in astrophysics or physics are eligible for the position. High proficiency in English is mandatory. Proven knowledge of the theory of non-radial oscillations of stars or of tides is an advantage. Furthermore, experience in student supervision is an asset for this position; the successful applicant will be expected to recruit and supervise students.

The application package should contain:

• A 1-page cover letter, indicating a motivational statement;
• A 2-page summary of previous research experience and achievements;
• A curriculum vitae, with a full publications list;
• The names and contact details of three references who are prepared to send confidential recommendation letters should they be requested to do so.

Members of minorities and underrepresented groups are strongly encouraged to apply.

The successful postdoctoral applicant will be offered a 2-year contract at IvS with a possible extension of 2 years depending on performance. Salary for this position will be commensurate to the standard scale for post-doc researchers in Belgium and will depend on the number of years of experience after PhD.

The offered contract will include social and medical insurance as well as pension rights. Working hours are flexible and the opportunity for teleworking maximally 2 days per week is offered. Refund of commuting expenses when using public transport or bicycle are included. The KU Leuven offers access to childcare.

The short-listed applicants will be invited for an interview on 2nd or 3rd September 2026. Decisions will be communicated by 9th September 2026, followed by a 1-week term to decide on acceptance or rejection of the offered position.

The preferred starting date for the position is 16th November 2026 or as soon as possible thereafter.
