A model of compact nuclei of galaxies as spherically symmetric star clusters far advanced to the state of statistical equilibrium is proposed. The systems of this kind are shown to be described by the Emden equation with polytropy index equal to 0.5, and with its help the main parameters of compact galactic nuclei are calculated. It is also shown that rapidly spinning neutron stars and white dwarfs are the main constituents of compact galactic nuclei if they age is of the same order as that of the Universe. It is concluded that the pulsars may be born by evaporation of neutron stars from the nucleus of our Galaxy. The number of such pulsars ought to be of the order of 3 cdot10^6.
