Abstract
The XMM-Newton spectra of the isolated neutron star RXJ0720 4-3125
obtained over 4 5 years show sinusoidal variations in the inferred
blackbody temperature the size of the emitting area and the depth of the
absorption line with a period of sim 7 1 years which we suggest to be
the precession period of the neutron star Precession of a neutron star
with two hot spots of different temperature and size probably not
located exactly in antipodal positions may account for the variations in
the X-ray spectra changes in the pulsed fraction shape of the light
curve and the phase-lag between soft and hard energy bands observed from
RX J0720 4-3125
