Abstract
I study the distribution of dark matter in dwarf spheroidal (dSph) galaxies by modelling their line-of-sight velocity dispersion profiles. Different dark matter profiles are considered, both cuspy and with flat density cores. The predictions are made in the framework of standard dynamical theory of two-component spherical systems with different anisotropy parameters. Comparison with observations for the Fornax dwarf shows that all dark matter profiles yield good fits but only profiles with cores are consistent with isotropic orbits.
