A Long Look at the Be/x-ray Binaries of the Small Magellanic Cloud
نویسنده
چکیده
We have monitored 41 Be/X-ray binary systems in the Small Magellanic Cloud over ∼ 9 years using PCA-RXTE data from a weekly survey program. The resulting light curves were analysed in search of orbital modulations with the result that 10 known orbital ephemerides were confirmed and refined, while 10 new ones where determined. A large number of X-ray orbital profiles are presented for the first time, showing similar characteristics over a wide range of orbital periods. Lastly, three pulsars: SXP46.4, SXP89.0 and SXP165 were found to be misidentifications of SXP46.6, SXP91.1 and SXP169, respectively. Subject headings: galaxies: individual (Small Magellanic Cloud) – pulsars: general – X-rays: binaries

Forty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملSpectral distribution of Be/X-ray binaries in the Small Magellanic Cloud
The spectral distributions of Be/X-ray binaries in the Large Magellanic Cloud and Galaxy have been shown to differ significantly from the distribution of isolated Be stars in the Galaxy. Population synthesis models can explain this difference in spectral distributions through substantial angular momentum loss from the binary system. In this work we explore the spectral distribution of Be/X-ray ...
متن کاملThe population of massive X - ray binaries ⋆ I . The Large Magellanic Cloud
We present high resolution blue spectroscopy of an almost complete sample of optical counterparts to massive X-ray binaries in the Large Magellanic Cloud (LMC) and derive their spectral classification. We find an spectral type B0II for the optical counterpart to RX J0532.5−6551, confirming it as the first wind-fed massive X-ray binary in the LMC. We also confirm the Be nature of the proposed co...
متن کاملLong-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 ...
متن کاملPhotometric Periodicities of Be/X-ray Pulsars in the Small Magellanic Cloud
Analysis of the longterm photometric variability of 7 Be/X-ray-pulsar systems in the Small Magellanic Cloud has been carried out. We find a variety of types of variability are present, including: longterm irregular changes, periodic orbital outbursts due to interaction between the stars (weeks to months), low-amplitude quasi-periodic variations of the equatorial disk (days), and nonradial pulsa...
