Discovery of extended infrared emission around the neutron star RX J0806.4-4123
B. Posselt, G. G. Pavlov, Ü. Ertan +3
Following up on a faint detection of a near-infrared (NIR) source at the position of the X-ray thermal isolated neutron star RX J0806.4-4123, we present new Hubble Space Telescope…
Optical excess of dim isolated neutron stars
Unal Ertan, Sirin Caliskan, M. Ali Alpar
The optical excess in the spectra of dim isolated neutron stars (XDINs) is a significant fraction of their rotational energy loss-rate. This is strikingly different from the situat…
On the X-ray Outbursts of Transient Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters
Sirin Caliskan, Unal Ertan
We show that the X-ray outburst light curves of four transient anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), namely XTE J1810-197, SGR 0501+4516, SGR 1627-41…
Anomalous X-ray pulsars: Persistent States with Fallback Disks
Unal Ertan, M. Ali Alpar, M. Hakan Erkut +2
The anomalous X-ray pulsar 4U 0142+61 was recently detected in the mid infrared bands with the SPITZER Observatory (Wang, Chakrabarty & Kaplan 2006). This observation is the first…
