AbstractWe examine the spectra of the persistent emission from anomalous X-ray pulsars (AXPs) and their variation with the spin-down rate Omega. Based on an accretion-powered model, the influences of both the magnetic field and the mass accretion rate on the spectral properties of AXPs are addressed. We then investigate the relation between the spectral property of AXPs and mass accretion rate A. The result shows that there exists a linear correlation between the photon index and the mass accretion rate: the spectral hardness increases with increasing A. A possible emission mechanism for the explanation of the spectral properties of AXPs is also discussed.
