Scientific paper

Within seven radio-quiet, thermally-emitting isolated NSs, RXJ 0720 is unique in that it shows long-term (~yrs) variations in its spectral parameters. Applying a phase-coherent timing solution with constant spin down leaves large residuals which may follow a cyclic pattern. The reasons for this behaviour is a matter of debate. Both a glitch and precession have been invoked, but present data do not allow to reach a firm conclusion. Most recent XMM observations show that the re- siduals probably reached a minimum of the cycle, while the spectral parameters evolution slowed down. The proposed observations will prove if the timing re- siduals follow a cyclic pattern and weather the spectral and timing variations are related. The outcome will rule out one of the two proposed scenarios
