Simple Model Of Accretion Onto Isolated Neutron Star With
Synchrotron Cooling
\end{center}


{\bf Abstract.}

In this work we modeled accretion onto the isolated
neutron star (INS) from the interstellar medium in the case of
spherical symmetry for different values of the magnetic field
strength, ambient gas density and NS's mass. We try to verify
the idea that if the radius of corotation, $R_{co}$,
is less than the Alfven radius, $R_A$ ,
the shell will form around the INS and $R_A$
will decrease to $R_{co}$ and the periodic X-ray source will appear
(see M.Colpi et al., 1993 A\&A 269, 319, hereafter CTL).
Dependence of $R_A$ from $t$ in our model coincides well with the
analytic formula from CTL. The periodic sources with $P$ from
several minutes to several months can appear.
