چکیده

An XMM-Newton target of opportunity observation of the field around the transient 18.37 s pulsar XTE J0055−727 in the Small Magellanic Cloud (SMC) revealed two bright, long-period X-ray pulsars in the EPIC data. A new pulsar, XMMU J005517.9−723853, with a pulse period of 701.7 ± 0.8 s was discovered and 500.0 ± 0.2 s pulsations were detected from XMMU J005455.4−724512 (= CXOU J005455.6−724510), confirming the period found in Chandra data. We derive X-ray positions of RA = 00 h 54 m 55.

XMM-Newton observations of the Small Magellanic Cloud: Be/X-ray binary pulsars

Aims. We analysed eight XMM-Newton observations toward the Small Magellanic Cloud (SMC), performed between October 2006 and June 2007, to investigate high mass X-ray binary systems. Methods. We produced images from the European Photon Imaging Cameras (EPIC) and extracted X-ray spectra and light curves in different energy bands from sources which yielded a sufficiently high number of counts for ...

Three New Long Period X-ray Pulsars Discovered in the Small Magellanic Cloud

The Small Magellanic Cloud is increasingly an invaluable laboratory for studying accreting and isolated X-ray pulsars. We add to the class of compact SMC objects by reporting the discovery of three new long period X-ray pulsars detected with the Chandra X-ray Observatory. The pulsars, with periods of 152, 304 and 565 seconds, all show hard X-ray spectra over the range from 0.6 7.5 keV. The sour...

Long-Term Behavior of X-ray Pulsars in the Small Magellanic Cloud

Results of a 4 year X-ray monitoring campaign of the SMC using the Rossi X-ray Timing Explorer (RXTE) are presented. This large dataset makes possible detailed investigation of a significant sample of SMC X-ray binaries. 8 new X-ray pulsars were discovered and a total of 20 different systems were detected. Spectral and timing parameters were obtained for 18. In the case of 10 pulsars, repeated ...

The discovery and study of the optical counterparts of the transient X – ray pulsars RX J 0052 . 1 – 7319 and XTE J 0111 . 2 – 7317 in the SMC ⋆

We report on the discovery and confirmation of the optical counterparts of the two transient X–ray pulsars, RX J0052.1–7319 and XTE J0111.2–7317. In the narrow (∼3 ′′ radius) X–ray error circle of RX J0052.1– 7319 we found a V = 14.6 (B − V = 0.1) 09.5IIIe (a classification as a B0Ve star is also possible, since the luminosity class depends on the uncertainty on the adopted reddening). Medium r...

X-ray Pulsars in the Small Magellanic Cloud

XMM-Newton archival data for the Small Magellanic Cloud have been examined for the presence of previously undetected X-ray pulsars. One such pulsar, with a period of 202 s, is detected. Its position is consistent with an early B star in the SMC and we identify it as a high mass X-ray binary (HMXB). In the course of this study we determined the pulse period of the possible AXP CXOU J010043.1-721...
