Postdoctoral Position on simulation and analysis techniques for exoplanet Characterisation
The Institute of Space Studies of Catalonia (IEEC) was established in February 1996 as a private non-profit foundation (NPO) to promote R&D in the space field in Catalonia. The IEEC is a research institute that studies all areas of knowledge and technologies applied to the space sector and space sciences, including astrophysics, cosmology, planetary science, Earth observation, navigation and space engineering. Its mission is to push the frontiers of space research from the scientific and technological fields for the maximum benefit of society. It should also be noted that the Foundation is attached to the Generalitat de Catalunya (Catalan Government) and forms part of its institutional public sector due to the fact that the Generalitat has a majority involvement in the entity.
Introduction
The object of this call is the selection process of a candidate to occupy the position of Postdoc Senior of the Area of the Space Sector of Catalonia of the Institute of Space Studies of Catalonia.
Description of position
- Position: 1 Postdoc Senior
- Professional group: Group III. Scientific Staff
- Professional category: Postdoc Senior
- Working hours: 37.5 hours/week
- Working location: In the headquarters of the Institut de Ciències de l'Espai located on the Campus of the Universitat Autónoma de Barcelona , C/Can Magrans 08193 Cerdanyola del Vallès,
Functions
Stellar activity poses a major limitation to the extraction of exoplanetary signals. An evolving and rotating inhomogeneous stellar surface hampers both the detection of the Keplerian motions of small planets in temperate orbits using Doppler radial velocities and the atmospheric characterization of exoplanets using transit spectroscopy. Our ability to account for these effects relies on modeling all the observables related to stellar activity as a function of time and wavelength.
The successful candidate will work on the development of methodologies to retrieve planetary signals (high-precision radial velocities and transit spectroscopy) from data affected by activity. A significant part of the work will focus on the evolution of the in-house stellar simulation software StarSim, and on its use to develop machine learning and algorithmic approaches to the inverse problem. For this reason, a solid background in Physics, Astronomy, and data analysis techniques is required. The successful candidate will have access to proprietary data from the CARMENES instrument, and potentially also from the CHEOPS mission, and will participate in the definition of the science exploitation of the future Ariel/ESA mission. Furthermore, they will have access to the (>20%) Spanish time in all the astronomical facilities at the Roque de los Muchachos Observatory and to the Calar Alto Observatory.
The successful candidate will join IEEC’s exoplanets group, which is composed of three world-leading senior researchers, plus ~2-3 postdocs, and ~3-5 PhD students. The group is led by Prof. Ignasi Ribas, who is the PI for the CARMENES Legacy-Plus survey and has a leading role in the Spanish contribution to space missions such as CHEOPS, Ariel and PLATO. The work will be co-supervised by Dr. Guillem Anglada-Escudé, who is an expert in exoplanet detection and has access to data from a variety of international collaborations.
Work will be performed at the Institute of Space Sciences (ICE), which is part of the Institute of Space Studies of Catalonia (IEEC), and located at the Autonomous University of Barcelona (UAB) campus. Due to its global nature, being a member of IEEC allows access to resources in other institutes working in astronomy and space in the Catalan ecosystem, as well as opportunities for extended collaborations. Also, the successful candidate will join the vibrant work environment of the UAB campus and access to all its facilities and services. The IEEC, the ICE, and the exoplanets group follow strict codes of respect and inclusion in all work practices. Women and members from minorities are strongly encouraged to apply.
- Submission deadline: All materials should be received by May 15 for full consideration
