The goal of this workshop is to provide participants with a fundamental understanding of the star clusters and initial mass function in a modern view. Star clusters have always played a prominent role in astrophysics. They are seen in a variety of galaxies with different masses, environments, and formation histories. Hence, they are considered the fundamental building blocks of galaxies and trace the star formation and assembly histories of their host galaxy. The aim of this workshop is to provide the students with a basic and robust understanding of the physical processes that govern the structure and evolution of stellar systems such as globular clusters and galaxies. Among these are two- and three-body processes, stellar evolution, tidal effects, and in extreme cases even gravitational radiation. We discuss the most recent and upcoming discoveries in the dynamics of star cluster, and introduce large astronomical surveys and observational approaches whereas using stars as probes of the Universe. Participants will develop knowledge of the astrophysics processes which explain the observed properties of star formation and evolution. Postdocs, PhD and MSc students are encouraged to participate in this workshop. The themes to be covered in the workshop are:

  • Dynamics of Collisional and Collisionless stellar systems
  • Stellar and Dynamical Evolution of Star Clusters
  • Direct N-body simulations in stellar systems
  • Two- and Three-body Processes, stellar evolution, tidal effects
  • Observations and formation scenarios
  • Multiple stellar populations in star clusters
  • From luminosity to mass functions
  • The IMF and Mass modelling in stellar clusters
  • The origin of brown dwarfs
