Abstract

The recent detection of the anomalous X-ray pulsar (AXP) 4U 0142+61 in the mid-infrared with the Spitzer observatory by Z. Wang and coworkers constitutes the first instance of a disk around an AXP. We show, by analyzing earlier optical and near-IR data together with the recent data, that the overall broadband data set can be reproduced by a single model of an irradiated and viscously heated disk.
