The Centre for Astrophysics and Gravitation, CENTRA, opens a call for 1 PhD Research Fellowship The work will take place at the Faculty of Sciences of the University of Lisbon (FCUL) under the supervision of Prof. André Moitinho. The duration of the fellowship is up to the maximum of four years (48 months), plus social security (first level contributions), personal accidents insurance and covers the costs of the FCUL PhD program fees. Scientific area: Astrophysics. The aim of the project is to investigate the processes that lead from a highly structured distribution of stars since their formation in clusters, to the smooth distribution observed in the field population of the Milky Way and of external galaxies. The work program is based on the exploration of data from the ESA Gaia mission and the numerical modelling of the dynamics and morphology of stellar systems.
