During August 19-23, 2013 Fesenkov Astrophysical Institute hosted the International Workshop MODEST-13. The MODEST (MOdeling DEnse STellar systems) is a loosely knit international collaboration between various groups working in stellar dynamics, stellar evolution, and related areas. One of the main activities of the collaboration is to provide a software framework for large-scale simulations of dense stellar systems, in which existing codes for dynamics, stellar evolution, and hydrodynamics can be easily coupled, and place them in the appropriate observational context. MODEST-13 is the thirteenth workshop within the MODEST initiative, the first major MODEST meeting in central Asia.

The topics of MODEST-13 workshop:

  1. Globular and dense clusters
  2. Central clusters in galaxies
  3. N-body simulations
