RX J0720.4-3125 AS A POSSIBLE EXAMPLE OF THE MAGNETIC FIELD
DECAY IN NEUTRON STARS, {\it by D.Yu. Konenkov and S.B. Popov.}

We studied possible evolution of the rotational period and the magnetic
field of the X-ray source RX J0720.4-3125 assuming this source to be an
isolated neutron star accreting interstellar medium. Magnetic field of the
source is estimated to be $10^6 - 10^9$ G, and it is difficult to explain
observable rotational period 8.38 s without invoking hypotesis on the
magnetic field decay. We used the model of ohmic decay of the the crustal
magnetic field. The estimates of accretion rate ($10^{-14} - 10^{-16}
M_{\odot}/{\rm yr}$), velocity of the source relative to interstellar
medium ($10 - 50 $ km/s), neutron star age
($2\cdot 10^9 - 10^{10}$ yrs) are obtained.
