Scientific paper

RX J0720 belongs to a group of seven radio-quiet isolated neutron stars with similar properties. It is unique in that it shows long term variations in its spectral parameters, like black body temperature, size of the emitting area and the depth of the absorption feature. Furthermore, a phase coherent pulse timing analysis assuming a constant spin period derivative shows large timing residuals. The cause of this enigmatic behaviour is still a matter of debate: cyclic variations are expected if the neutron star precesses while a sudden event like a glitch may cause a gradual evolution after a relatively fast change. The recent results from our XMM-Newton observations indicate that the timing residuals follow an abs(sine) behaviour with the minimum expected around next year.
