Re-examining the X-ray versus spin-down luminosity correlation of rotation powered pulsars

The empirical relation between the X-ray luminosity (in the 2{10 keV band) and the rate of spin-down energy loss Lsd of a sample of 39 pulsars is re-examined considering recent data from ASCA, RXTE, BeppoSAX, Chandra ,a ndXMM-Newton and including statistical and systematic errors. The data show a signicant scatter around an average correlation between Lx;(2 10) and Lsd. By tting a dependence of Lx;(2 10) on the period P and period derivative _ P of the type Lx;(2 10)/ P a _
