Abstract

We show that the irradiated accretion disk model can account for all the optical and infrared observations of the anomalous X-ray pulsars in the persistent state. While placing an upper limit on the inner disk radii, and thus on the strength of the dipole component of the stellar magnetic field, the model fits do not constrain the outer disk radii. And while magnetar fields (G) in higher multipoles are compatible with the irradiated B. > 10/14 disk model, magnetic dipole components of magnetar strength are not consistent with optical data.
