[交流] 【招聘】PhD position in astrochemistry 已有3人参与

Photodissociation and excitation of molecules in protoplanetary disks
   =====================================================================

            Prof.dr. E.F. van Dishoeck
         Leiden Observatory, Leiden University, the Netherlands

A 4-year PhD (AIO) position is available to study the
photodissociation and excitation of astrophysically relevant small
molecules in protoplanetary disks. The project is part of an
interdisciplinary collaboration between astronomers and chemists in
the context of the Dutch Astrochemistry Network.  Determining the
physical and chemical structure of planet-forming disks is a major
goal of new large observational facilities such as the Atacama Large
Millimeter Array (ALMA), the James Webb Space Telescope (JWST) and the
European Extremely Large Telescope (E-ELT). Photodissociation of
molecules in the upper layers of the disk is a key process in setting
their chemical structure.  The aim of the project is to investigate
the chemical processes and integrate the resulting rates and product
branching ratios into protoplanetary disk models. The model results
will be compared with existing and future observational data. The
initial focus will be on the N2 molecule, a key species in the
nitrogen chemistry. Also, the excitation of molecules like CO and OH
will be studied using newly determined collisional rate coefficients.

Applications should include a curriculum vitae (with a list of grades
for exams), a brief statement of research experience, and the names of
at least two people who can serve as a reference. Selection of
candidates will start on September 25 2010 and will continue until the
position is filled.  The positions are open to students of all
nationalities with the equivalent of a Masters degree in astronomy,
physics or chemistry. The starting date for the positions can be
anytime up to March 2011.  Please submit applications through:
