The anomalous x-ray pulsar 4U 0142+61: a neutron star with a gaseous fallback disk
Ertan, Ünal and Ekşi, Kazım Yavuz and Erkut, M. Hakan and Alpar, M. Ali (2006) The anomalous x-ray pulsar 4U 0142+61: a neutron star with a gaseous fallback disk. In: Isolated Neutron Stars from the Interior to the Surface, London, UK (Accepted/In Press)
The recent detection of the anomalous X-ray pulsar (AXP) 4U 0142+61 in the mid infrared with the Spitzer Observatory (Wang, Chakrabarty & Kaplan 2006) constitutes the first instance for a disk around an AXP. We show, by analyzing earlier optical and near IR data together with the recent data, that the overall broad band data can be reproduced by a single irradiated and viscously heated disk model.
