Stars form in groups or clusters that are far denser than galactic
fields. Understanding the dynamical processes within these dense
stellar systems is therefore important for understanding the
properties of stellar populations of galaxies.
This course gives an outline of the birth and dynamical evolution of
star clusters, and of the dynamical processes acting within dense
stellar systems. These include energy equipartition, destruction of
binary systems and the acceleration of stars to high energies.
Knowledge of these issues is essential for an understanding of star
formation as well as of the distribution of stars on galactic scales
because most stars are born in clusters.

Comments:
This course provides an introduction to the numerical procedures used
in the three areas of stellar dynamics: planetary dynamics,
star-cluster dynamics and galactic dynamics. A few optional numerical
problems/tasks will be available.

Learn to use Sverre Aarseth's Nbody6 ("collisional") code for
star-cluster applications (e.g. massive stars in cluster cores,
evaporation of brown dwarfs, evolution of young clusters)
Learn to use the Bien/Fellhauer/Kroupa/Metz Superox/Superbox++
("collisionless") code for galactic-dynamics problems
(e.g. evolution of satellite galaxies, galaxy-galaxy encounters,
massive star-cluster complexes)
Comments:
The learning sessions take place with other students/postdocs
acquainted with the codes, and intend to prepare the participants
for research problems needing stellar dynamics as a tool
(e.g. for the interpretation of GAIA data).

organised and lead by Andreas Kuepper and Seungkyung Oh, on the 3rd
floor of the Argelander-Institute.
