Scientific paper

We consider the sample of weakly active galactic nuclei from the Local Universe. We apply the Bondi model to describe the dynamics of the accreting gas and we calculate the emerging radiation spectra and the effective efficiency of the flow. We show that in most cases the Bondi flow does not predict the observed X-ray luminosities LX when equipartition of the gas pressure with magnetic field is assumed. Nevertheless, in some cases LX can be fitted to the data while changing model parameters.
