Scientific paper

RX J0720.4-3125 belongs to a group of radio-quiet isolated neutron stars, whose X-ray spectra consist of broad absorption feature(s) superimposed on a blackbody continuum. It is unique in that its spectrum and flux are time variable. The cause for this is unclear, but one possibility is free precession of two different hot spots at the star surface. Free precession can reveal important information on the star s interior structure. However, the last observation shows that the spectral evolution does not follow the prediction of a simple sinusoidal model. Continued monitoring of the spectral and timing properties is needed to reveal whether this is due to a complex and patchy surface thermal map or whether the variation is caused by effects different from precession.
