The Exoplanet Group at DTU Space at the Technical University of Denmark, situated in the greater Copenhagen area, invites applications from highly qualified individuals for a postdoctoral position of three-year duration in atmospheric characterization of terrestrial, super-Earth, and sub-Neptune type exoplanets.
You will work with Prof. Lars A. Buchhave and Dr. Alexander Rathcke in the rapidly growing Exoplanet Group at DTU Space. Our group leads JWST programs and has had multiple proposals accepted from our group (GO 2420, GO 3730, GO 7675). Through international collaborations, we are also deeply involved in several other JWST programs.

Additional information about the Exoplanet Group at DTU Space can be found at http://www.exoplanets.dk.
Responsibilities and qualifications
We are seeking a talented and highly motivated researcher to work at the forefront of exoplanet atmospheric science with JWST. The postdoc will be involved with the analysis and interpretation of JWST data (new data and/or public archival data) for terrestrial and sub-Neptune exoplanets, including transmission and emission spectroscopy (e.g., from JWST/NIRSpec and JWST/MIRI) with the goal of advancing our understanding of the environments and atmospheres of small planets (terrestrial, super-Earth, and sub-Neptunes).

| Postdoctoral position (m/f/d) in fast transient astronomy as part of the DFG-funded dynaverse Excellence Cluster | Closing date: 2026-01-09
Contact: Dr. Laura Spitler |
| The Max Planck Institute for Radio Astronomy (MPIfR) invites applications for a postdoctoral position (m/f/d) to work in the dynaverse Excellence Cluster funded by the German Research Foundation (DFG). The successful applicant will work in the Fundamental Physics in Radio Astronomy department and Lise Meitner Research Group. | | ▸ more | The astrophysical sources of fast transient emission, observable as fast radio bursts (FRBs) or pulsars, are laboratories for extreme physics as well as useful astrophysical probes. FRBs are highly luminous radio flashes that originate from so-far unidentified extragalactic sources. Large-scale surveys are aiming to unlock their origin, as well as use them for many astrophysical applications including measuring the distribution of ionized baryons and expansion of the Universe. Radio pulsars are neutron stars in our own galaxy, and through precise radio timing, they can be used to test theories of gravity and measure the equation of state.
Advances in our understanding of the astrophysics of fast transient sources, as well as finding increasingly powerful astronomical ?tools?, requires searching for and discovering new sources. Each generation of survey pushes the boundaries of the previous generation with, for example, more sensitivity, wider bandwidths, higher time resolution, or larger fields-of-view. These advances come with a commensurate increase in complexity and, in particular, the number of candidates. Zeroing in on the true, astrophysical candidates is a computational needle in a haystack. To tackle these ?big data? challenges, astronomers have begun to employ machine learning techniques.
The application of machine learning in astronomy is at the core of the new field of astroinformatics. One goal of the new DFG-funded dynaverse Excellence Cluster is to bring together experts in radio astronomy and machine learning to make the Cologne-Bonn region a world-wide leader in astroinformatics.
The successful candidate will develop new ML techniques for the classification of FRB or pulsar candidates in large-scale survey data and apply these to new data and then lead the scientific analysis of the resulting discoveries. He or she will also have the opportunity to co-supervise students and contribute to the scientific exchange within the department.
Necessary skills:
- A Ph.D. in physics, astronomy, computer science or a related field by the appointment date
- Prior experience with radio astronomy observations and data analysis
- Strong proficiency and experience in scripting/programming, in particular in Python
- Strong interest in programmatic problem solving and developing pipelines
- Strong proficiency in the Linux operating system
- Enthusiasm for disseminating results in scientific publications and conferences
- Enthusiasm working in a large, international team
Desired skills (one or more of):
- Prior experience with standard software used for FRB or pulsar searches and analysis
- Practical experience in applying Machine Learning methods to data
- Experience with computer clusters and HPC
- Willingness to supervise Masters/PhD students
Apllication process:
Interested and qualified individuals are encouraged to apply by submitting a curriculum vita, a list of publications, research statement (max 2 pages), and have at least two letters of recommendation sent to the MPIfR application portal (see link below) before 17:00 UTC (18:00 CET) on January 9, 2026. After submission, shortlisted applicants will go through an online interview process before selecting the most suitable candidate. We expect this process to be done by mid February 2026.
https://jobs.b-ite.com/en/jobposting/bc719cb283fb26939679dd013d2420f58e61d1120/apply
Appointments will initially be for 2 years, with the possibility of further extension of one more year based on mutual agreement and funding availability. The preferred starting time of the candidate is between April 2026 and August 2026, but this is open for negotiation. We have dedicated funds for the postdoc to present their work in national and international conferences.
Remuneration is within the framework of the German wage agreement for the public system (TVöD-Bund), which includes comprehensive healthcare coverage and other social benefits.
The Max Planck Society and our group are committed to increasing the number of individuals with disabilities in its workforce and therefore encourage applications from such qualified individuals. Furthermore, we seek to increase the number of women and other gender minorities in areas where they are underrepresented and therefore such people are particularly encouraged to apply. The Max Planck Society and our group encourage diversity in its work culture. People from all backgrounds and genders are invited to apply.

Contact: Jean-Francois Donati |
| We invite applications for a 2-3yr postdoc position on modeling magnetic fields of M dwarfs at the Institut de Recherche en Astrophysique et Planétologie (IRAP) located in Toulouse, France, within the SPIRou science consortium coordinated by Drs JF Donati and C Moutou in Toulouse. | | ▸ more | This project aims at modeling the evolving magnetic topologies of M dwarfs, monitored with the SPIRou near-infrared spectropolarimeter at the Canada-France-Hawaii Telescope since 2019 in the framework of the SPIRou Large Programs. More specifically, the goal is to exploit an advanced version of Zeeman-Doppler imaging incorporating temporal evolution, to the existing and future SPIRou data collected for a few tens of M dwarfs of various masses, to infer fresh constraints on the dynamo processes operating in largely and fully convective stars. The work will take place at IRAP with Drs JF Donati and C Moutou, starting Q1 2026.
In addition to a PhD in astrophysics, the candidates must have a solid background in stellar magnetic fields and spectropolarimetry, to efficiently analyse data sets collected with SPIRou using the tomographic technique of Zeeman-Doppler imaging, and to reconstruct the parent magnetic topology at the surface of the star. Experience in velocimetry is also welcome.
The candidates should provide the following documents (PDF only, accessible via a file server) by 2026 Jan 15 :
* a motivation letter (max 2 pages),
* a description of past and current research statements (max 5 pages),
* a CV (max 2 pages)
* a publication list,
* 3 reference letters to be sent directly by the mentors (same deadline)
to Drs JF Donati (jean-francois.donati @ irap.omp.eu) and C Moutou (claire.moutou @ irap.omp.eu). Short-listed candidates will be invited for an on-line interview ~2 weeks after the deadline.
