Título:  Two Postdoctoral Contracts Exoplanets and Astrobiology 2023 (PS-2023-076)

Centro:  Instituto de Astrofísica de Canarias

Tipo:  Postdoctoral

descripción: 

The IAC (Tenerife) announces TWO postdoctoral contracts to work on the project linked to the line of research “Exoplanets and Astrobiology: preparatory science for the ARIEL mission”. The contract s are funded by the project “Science and Technology for the ARIEL Mission: IAC Contribution” (PID2021-125627OB-C32), led by Prof. Enric Palle.

Research topics at the IAC include most areas of astrophysics: Solar Physics (FS), Exoplanetary System and Solar System (SEYSS), Stellar and Interstellar Physics (FEEI), The Milky Way and The Local Group (MWLG), Formation and Evolution of Galaxies (FYEG), and Cosmology and Astroparticles (CYA-CTA). All of these are supported by an ambitious instrumentation programme. In 2020, the IAC was granted by the Spanish Government the status of Severo Ochoa Center of Excellence, a prestigious recognition awarded for the third time to the IAC as a leading research institute in Spain. Further information about the IAC's research programme, its Observatories and the 10.4m GTC is available at the IAC's web page: https://www.iac.es/

Tasks: The “Exoplanets and Astrobiology” group at IAC participates in the Guaranteed Time Observations (GTO) programs of the MUSCAT2 collaboration, the CHEOPS satellite and the CARMENES and ESPRESSO spectrographs. We have a leading role in the development of the ARIEL and PLATO space missions, as well as the ANDES spectrograph for the ELT. Finally, we are also involved in the follow-up of the TESS mission, and have a lively research team in the area of planetary atmospheres characterization

The successful candidate will pursue research in the following fields:

• Characterization of exoplanet atmospheres by means of high-resolution spectroscopy using spectrographs such as HARPS-N, GIANO, CARMENES and/or ESPRESSO, or by means of low resolution spectrographs using 8-10 m class telescopes.
• Ground-based follow-up of the TESS mission. Our group is heavily involved in the TESS mission follow-up efforts, with hundreds of dedicated telescope nights, including photometric and radial velocity measurements.
• Analysis and observations of rocky planets with the JWST, and the use of molecular mapping for the analysis of atmospheres of giant planets with the JWST.
• Biomarkers and habitability of Earth-like planets

Particular attention will be given to applicants with experience in the field of exoplanet characterization, with a strong publication record. The leadership capacity, demonstrated in the achievement of original lines of research, successful observing proposals or by obtaining funding will also be valued.

Requirements: The candidates must have an excellent research record, commensurate with the duration of their research career. They must be in possession of a Ph.D. degree in Astrophysics or Physics by the application deadline. Candidates who have not received their doctorate before the deadline will not be admitted to the selection process. Applicants who prepared their thesis at the IAC have to present accreditations of complementary training at other research centers (this period should be either 1 continuous year or 18 accumulated months) by the application deadline. The IAC is an equal-opportunity employer. We encourage, in particular, applications by women and by members of minorities.

Título:  One Postdoctoral Contract Primitive Objects of the Solar System 2023 (PS-2023-073)

Centro:  Instituto de Astrofísica de Canarias

Tipo:  Postdoctoral

descripción: 

The IAC (Tenerife) announces ONE postdoctoral contract to work on the project linked to the line of research “Small bodies of the Solar System: primitive objects”. The contract is funded by the project “Hidrated minerals and organic compound in promitive - MinHiCAP” (PID2020-120464GB-I100) lead by Dr. Dr. Javier Licandro and Dr. Julia de León.

Research topics at the IAC include most areas of astrophysics: Solar Physics (FS), Exoplanetary System and Solar System (SEYSS), Stellar and Interstellar Physics (FEEI), The Milky Way and The Local Group (MWLG), Formation and Evolution of Galaxies (FYEG), and Cosmology and Astroparticles (CYA-CTA). All of these are supported by an ambitious instrumentation programme. In 2020, the IAC was granted by the Spanish Government the status of Severo Ochoa Center of Excellence, a prestigious recognition awarded for the third time to the IAC as a leading research institute in Spain. Further information about the IAC's research programme, its Observatories and the 10.4m GTC is available at the IAC's web page: https://www.iac.es/

Tasks: The successful candidate will pursue research in the following fields:

• Compositional characterization of small primitive bodies from the analysis of spectroscopic and photometric data, from the near-ultraviolet to the infrared wavelengths
• Scientific exploitation of the spectral data of small bodies provided by Gaia and spectro-photometric data of these objects provided by LSST, ESA-Euclid, J-PLUS (and similar surveys)
• Scientific exploitation of mid- and near-infrared spectroscopic data of small primitive bodies obtained with the James Webb Space Telescope (JWST) in the projects in which Solar System Group is involved. Preparation of new observational proposals for these objects for the JWST and for other telescopes in the Canary Islands Observatories in support of these observations, analysis and scientific exploitation of the data obtained.
• Scientific exploitation of the data obtained by space missions that have visited primive small bodies (i.e. OSIRIS-REx, Hayabusa2, etc.)

Particular attention will be paid to applicants with experience in the field of spectroscopy of small bodies in the Solar System at different wavelengths and in the exploitation of large astronomical databases.

Requirements: The candidates must have an excellent research record, commensurate with the duration of their research career. They must be in possession of a Ph.D. degree in Astrophysics or Physics by the application deadline. Candidates who have not received their doctorate before the deadline will not be admitted to the selection process. Applicants who prepared their thesis at the IAC have to present accreditations of complementary training at other research centers (this period should be either 1 continuous year or 18 accumulated months) by the application deadline.

Título:  The Atmospheric Composition of the Ice Giants Uranus and Neptune

Centro:  Institut Origines (Aix-Marseille University)

Tipo:  Predoctoral

descripción: 

A PhD scholarship opportunity is open as part of the Institut Origines (Aix-Marseille University, Laboratoire d'Astrophysique de Marseille), in Marseille, France. The successful candidate will understand and model the abundance profiles of the main volatile species in Uranus and Neptune using numerical simulations to prepare the future exploration of these worlds by a spacecraft mission. The abundance distributions of key chemical species across the planet provide information about the planet’s deep chemical inventory, bringing constraints on the planet formation scenario. Such model predictions are necessary to interpret in-situ measurements performed by entry probes. These distributions also contain the signature of the planet transport processes, and are important to understand how the planet interact with its local environment. The PhD position will be supervised by V. Hue and O. Mousis. The candidate will work in the interdisciplinary environment of the Institut Origines, which will provide opportunities for expanding their knowledge.

The funding is available for a period of three years. The start date would be October to December 2023, depending on the availability of the applicant. Applicants must hold a Master's degree in physics, astrophysics, planetary science, or computer science at the time of appointment. Applicants should submit a letter of motivation, a CV, a list of publications (if available), degrees certification, and request a letter of recommendation. Review of applications will begin upon receipt until the position is filled. All applications received by the deadline will be given full consideration.

Application Deadline: August 1st, 2023
