چکیده

We report optical and IR observations of the ASCA X-ray pulsar system AX J0051-733. The relationship between the X-ray source and possible optical counterparts is discussed. Long term optical data from over 7 years are presented which reveal both a 1.4d modulation and an unusually rapid change in this possible binary period. Various models are discussed.

Chandra Observations of the Transient 7 - S X - Ray Pulsar Ax J 1845 . 0 − 0258

We present the results of Chandra X-ray Observatory observations of the transient anomalous X-ray pulsar candidate AX J1845.0−0258 in apparent quiescence. Within the source’s error circle, we find a point source and possible counterpart, which we designate CXOU J184454.6−025653. No coherent pulsations are detected, and no extended emission is seen. The source’s spectrum is equally well describe...

XMM-Newton observations of the Small Magellanic Cloud: XMMU J004814.1-731003, a 25.55 s Be/X-ray binary pulsar

Aims. To investigate candidates for Be/X-ray binaries in the Small Magellanic Cloud (SMC), we observed a region around the emission nebula N19 with XMM-Newton in October 2006. Methods. We analysed the EPIC data of the detected point sources to derive their spectral and temporal characteristics. Results. We detected X-ray pulsations with a period of 25.550(2) s from the second-brightest source i...

Discovery of an X - Ray Pulsar in the SMC : AX J 0058 − 7203

We report on the discovery and analysis of an X-ray pulsar, AX J0058−7203, in the Small Magellanic Cloud. This pulsar exhibits coherent pulsations at P = 280.3 s with a double-peak structure. The X-ray spectrum is well fitted with a simple power-law model of photon index Γ ∼ 0.7. No significant change of the pulsation period over the observation was found. A comparison with ROSAT observations i...

A multi-frequency identification study of the SMC X-ray binary AX J0049-732

We present a high-resolution multi-frequency identification study of the Small Magellanic Cloud (SMC) region around the newly discovered X-ray pulsar AX J0049-732. ROSAT PSPC images show three X-ray sources near the ASCA source position. We combine X-ray, radio-continuum and optical data to identify these sources. RX J0049.2-7311 and RX J0049.5-7310 did not show long-term time variability nor p...

A multi-frequency study of the SMC region around AX J0105-722

We present a high-resolution multi-frequency study of the Small Magellanic Cloud (SMC) region around the X-ray pulsar AX J0105-722. From ROSAT PSPC images we resolve this source into several X-ray sources. We combine X-ray, radio-continuum and optical data to identify the sources: for RX J0105.1-7211 we propose an emission line star from the catalogue of Meyssonier & Azzopardi (1993) in the X-r...
