Abstract
This paper describes the developed model of dark matter cored density profiles. This model was recently proposed by Dmytro Iakubovskyi (Iakubovskyi & Rudakovskyi, in preparation). It has only one extra parameter – the maximal value fmax of phase-space distribution function – that turn a cusped Navarro-Frenk-White density profile into a cored one. This paper focuses on the estimation of the influence of velocity anisotropy on the cored density profile by using the Osipkov-Merritt model. The density profiles of the typical dwarf-spheroidal galaxy for different masses of fermionic dark matter particle and different anisotropy parameters ra was calculated. It was obtained that the influence of velocity anisotropy on the cored density profile is small.
