Missions

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.

Activités

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.

Compétences

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.
