The high energy emission of radio pulsars provides interesting information about the extreme temperatures of the neutron stars and the accelerated particles around them. As neutron stars age they become less powerful, but surprisingly more efficient X-ray emitters. The X-ray properties of old pulsars are not well understood.

I will present our recent spectral and timing results of an X-ray study of  PSR J0108-1431 with XMM-Newton. PSR J0108-1431 is the oldest and closest of the X-ray detected rotation-powered pulsars. I will discuss our results with respect to past studies of other old (and young) pulsars.
