Abstract
We show that the observed pulsed optical emission of the anomalous X-ray pulsar 4U 0142+61 can be accounted for by both the magnetar outer gap models and the disk-star dynamo gap models, therefore is not an evidence in favor of one of these models as its responsible mechanism. Nevertheless, the estimated high energy gamma-ray spectra from these models have different power-low indices, and can be tested by future observations of the Gamma-ray Large-Area Space Telescope (GLAST). Furthermore, we show by analytical estimations that the expectations of a standard disk model is in agreement with the observed unpulsed optical and infrared luminosities of the AXP 4U 0142+61.Keywords
