Exoplanets detection and characterization in direct imaging

The COBREX ERC project ains at the detection in direct imaging and characterisation of extrasolar planets for the first time in the 5-10 au region. To meet these objectives, we are looking for a postdoc to lead an ambitious reduction and analysis programme, using hundreds of young stars from archival and future observations, to make individual studies as well as a statistical analysis of the results in the context of planet formation and evolution.

The Post-doc will work at LESIA (Observatoire de Paris-Meudon), offering a rich scientific environment, with experts in High Contrast Imaging, Interferometry and planetary science, disks, exoplanet atmospheres and stellar physics, in close collaboration with COBREX colleagues from IPAG (Grenoble), CRAL (Lyoc), and OCA (NICE), currently gathers more than 10 astronomers, 4 PhD students and 1 post-doc. 2 post-docs are expected to join the team in 2022. Regular visits to Grenoble, where the COBREX Data Center is located, will be necessary.

Postdoc missions:

• Developing new imaging algorithms, including with machine learning
• Running these algorithms on large datasets
• Study of individual systems and exoplanets
• Interpreting the results: statistical studies, comparison with planet formation models.
• Observations with the ESO VLT, JWST if needed

• Supervising students.

Expected Skills:

PhD in astrophysics, planetary sciences

- Knowledge in statistical analysis (formalism, biases, algorithms) and Data Science required.

- Knowledge in data reduction algorithm development and computation. Knowledge in AI (if possible).

- Languages: python

- Working language is English. French is not mandatory

- Values: enthusiasm, tenacity, creativity, team spirit
