LATE PROJECT: All applicants who have applied this year will be automatically considered also for this project.

Star clusters represent the essential building blocks of our Universe – stars are born in them and they supply the fields of the host galaxies with stars during their evolution.

The PhD project is focused primarily on the evolution of star clusters which is to be studied mostly numerically, using direct N-body modelling, but also by means of simple analytical models where applicable. Confrontation of the obtained results with the most up-to-date observational data provided by the Gaia satellite will be an essential part of the work. Specific topics to be addressed include star cluster collisions and rotation, properties of the star cluster population in our Galaxy, and internal dynamics of nuclear star clusters hosting a supermassive black hole at their centres with a particular focus on the centre of our Galaxy.

The PhD student will naturally collaborate within the well established star cluster group at the Astronomical Institute of Charles University: Pavel Kroupa, Ladislav Subr, Henriette Wirth.
