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

Abstract (from CDS):

The empirical relation between the X-ray luminosity (in the 2-10keV 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, and XMM-Newton and including statistical and systematic errors. The data show a significant scatter around an average correlation between Lx,(2–10) and Lsd. By fitting a dependence of Lx,(2–10) on the period P and period derivative {dot}(P) of the type Lx,(2–10)∝Pa[{dot}(P)]b, we obtain a=-4.00 and b=+1.34 (i.e. a≃-3b). This translates into the relation Lx,(2–10)=Lx,nor(Lsd/erg.s–1)1.34 with a normalization Lx,nor=10–15.3erg/s . However, the reduced χ2 is large (=7.2) making the fit unacceptable on statistical ground. All the X-ray luminosities lie below a critical line Lx,crit: the corresponding efficiency of conversion of rotational energy into 2-10keV X-rays is η_
