| Sulphur-bearing molecules in star forming regions: Observational and laboratory investigations | Closing date: 2018-06-01
Contact: Francois Dulieu |
| The interstellar medium is filled with molecules, particularly in dense molecular clouds where also stars and planets form. Understanding the origin of these molecules requires a combination of state-of-the-art astrochemical experiments and observations of molecules in space. This thesis aims at tackling a longstanding problem in astrochemistry, the Sulphur chemistry in star-forming regions, particularly the origin of H2S in ices, as well as its link with other observed forms in space. Half of the work will be devoted to laboratory astrophysics. | | ▸ more | Subject: Sulphur-bearing molecules in star forming regions: Observational and laboratory investigations.
Supervisors: F. Dulieu (LERMA, University of Cergy-Pontoise & Paris Observatory), co- supervised by L. E. Kristensen (Centre for Star and Planet Formation, Niels Bohr Institute & Natural History Museum of Denmark, University of Copenhagen)
Thesis: The interstellar medium is filled with molecules, particularly in dense molecular clouds where also stars and planets form. Understanding the origin of these molecules requires a combination of state-of-the-art astrochemical experiments and observations of molecules in space. This thesis aims at tackling a longstanding problem in astrochemistry, the Sulphur chemistry in star-forming regions, particularly the origin of H2S in ices, as well as its link with other observed forms in space. Half of the work will be devoted to laboratory astrophysics. Using the experimental set-ups located in Neuville-sur-Oise (FORMOLISM and VENUS), the synthesis of H2S and the properties of the ice formed will be investigated. The experimental work will be done with the team (https://lerma.obspm.fr/spip.php?article48). The other half will be devoted to the analysis of observations of Sulphur-bearing molecules in star-forming regions, and will be done as part of an extended visit to Copenhagen.
Practical details
The grant will be a doctoral contract which is a 3-year working contract following French/European regulations (1758? monthly gross salary). The student will follow the courses and regulations of Doctoral School of Science and Engineering of Paris Seine University, (ED 417 http://www.collegedoctoral.u-cergy.fr/). The starting date is as soon as possible.
Application
Applicants must have a master degree in Science, particularly astrophysics, physics or chemistry. Any practical experience (Internship, master diploma...) in radioastronomy or experimental physics is an effective positive aspect of the application.
Applicants must have excellent communication skills in English (oral and written), which will be the working language; non-French students will follow French language training (part of the Doctoral School educational program).
Applications should consist of a detailed CV, a letter of motivation and a letter of intent. The candidate should furthermore arrange for a recommendation letter from a professor familiar with the applicant to be sent to both Prof. Dulieu and Dr. Kristensen. Applications will continue to be considered until the position is filled.
