GREAT-ITN Recruitment: Leiden Observatory, University of Leiden

Project Title: Dynamical Evolution of Clusters

Applications will be accepted until the post is filled.

The LEID ESR will perform a detailed study of the dynamical evolution of clusters in a sophisticated Galactic potential, containing contributions from the bar, spiral arms, molecular clouds, and disk warps. This detailed understanding of cluster migration and dissolution will enable answers to a range of questions. Can the Milky Way disks indeed be explained as having been built up from stars formed in clusters? How do clusters migrate within the disk and how does this affect, e.g., age and metallicity gradients? How can our understanding of cluster migration and dissolution be exploited to enhance the interpretation of abundance data and vice versa? Can cluster orbits be traced back reliably to their place of birth? Can individual stars in moving groups be traced to their parent cluster? In particular can we do this for the Sun and find its siblings?

Important Eligibility Information concerning ESRs:

Early-stage researchers are those who are, at the time of selection by the host institution, in the first four years (full time equivalent) of their research careers. This is measured from the date when they obtained the degree which formally entitles them to embark on a doctorate, either in the country in which the degree was obtained or in the country in which the research training is provided, irrespective of whether or not a doctorate was envisaged. Researchers are normally required to undertake trans-national mobility (i.e. move from one country to another) when taking up their appointment. One general rule applies to the appointment of researchers in a network:

At the time of selection by the host organisation, researchers must not have resided or carried out their main activity (work, studies, etc.) in the country of their host organisation for more than 12 months in the 3 years immediately prior to their recruitment. Short stays, such as holidays, are not taken into account. As far as international European interest organisations or international organisations are concerned, this rule does not apply to the hosting of eligible researchers, however the appointed researcher must not have spent more than 12 months in the 3 years immediately prior to the selection by the host organisation in the same appointing organisation.
