Ukrainian Journal of Physics| Резюме: | The dynamical friction force acting on a spatially extended probe (globular clusters and dwarf galaxies) moving in the environment of ultralight bosonic dark matter in the state of the Bose–Einstein condensate is determined. Modelling the probe as a r sphere of radius lp, the radial and tangential components of the dynamic friction force are found in an analytic form, which reduces in the limit lp → 0 to the corresponding analytic expressions obtained in the literature in the case of a point probe. The dependence of dynamical friction force on boson particle mass was analyzed and found to be non-monotonous in the interval 10−23÷10−21 eV. |
