Two-year postdoc in Toulouse: Near-infrared radial velocities for the characterization of nearby exoplanet systems | Closing date: 2025-09-30 Contact: Claire Moutou |
The objective of the 2-year postdoc is to investigate near-infrared precise radial velocity (RV) time series of cool stars obtained with SPIRou at Canada-France-Hawai?i Telescope. The position is based at IRAP (Institut de Recherche en Astrophysique et Planétologie) in Toulouse, South France while the project collaboration includes research teams in Grenoble and Marseille. | ▸ more | SPIRou is a spectrograph and spectropolarimeter covering the 980-2450nm waveband at high spectral resolution in one shot and it is optimized for RV measurements at a precision of 1-2 m/s.?
For this position, an expertise in RV measurements and/or in machine learning processing is required. Knowledge in stellar spectropolarimetry, magnetic fields, or stellar activity is welcome but not mandatory. The SPIRou data has been collected since 2019 in large surveys which consisted in the monitoring of about 80 nearby cool stars. The objective is to explore further the characteristics of noise and planetary signals present in the data, using innovative methods.
The postdoctoral position is offered in the framework of the ANR project ORVET.
The position can start in January 2026 with about two year duration depending on the candidate?s experience. Interested candidates should have a PhD in Astrophysics or Data Processing / Machine Learning and are requested to send to claire.moutou @ irap.omp.eu the following documents by September 30, 2025:
-a CV including their list of publications
-a 2-page letter of their expertise and research ideas
-contact information for two referees
