DESCRIPTION:Speakers: Galina Shchelkanova (NRC "Kurchatov institute" - ITE
 P)\nWe present nearly self-consistent stellar-halo models of the dwarf sph
 eroidal Fornax galaxy the satellite of the Milky Way galaxy. Such galaxies
  are dark matter dominated objects with almost no gas in them so they are 
 excellent objects for N-body modelling that takes into account visible and
  dark matter(DM) halo components. Three models are self-consistent realiza
 tions containing a truncated King or Plummer models bulge (it stands for t
 he stellar component of the galaxy) and the lowered Evans dark halo model.
  These components are given by the distribution functions which are the fu
 nctions of $E$ and $L_z$ only. And four models with the King and Plummer v
 isible components are made by the AGAMA code based on the calculation of o
 rbits. To guess the parameters which make the N-body models close to the v
 isible object we use hydrodynamic stellar-dark model of the Fornax galaxy 
 taking into account the velocity anisotropy parameter. The AGAMA models sh
 ow better agreement of the resulting velocity dispersion profiles with the
  observed data. We also traced the evolution of all these models and found
  them rather stable during several typical dynamical times.\n\nhttps://ind
