Letter to the Editor BeppoSAX observations of a new X-ray burster in the Galactic Center region, possibly coincident with a recurrent transient
We report BeppoSAX NFI observations of the X-ray source SAX J1747.0–2853 recently discovered in the region of the Galactic Center. The presence of type I X-ray bursts indicates that this source, positionally coincident with the transient GX 0.2–0.2 observed in 1976, is a neutron star accreting from a low mass companion.
متن کاملThe ultra-compact binary 4U 1850−087 observed with INTEGRAL: hard X–ray emission from an X–ray burster
Context. The X–ray burster 4U 1850−087, located in the Galactic globular cluster NGC 6712, is an ultracompact binary (orbital period ∼21 minutes), likely harbouring a degenerate companion. Aims. The source has been observed at soft γ-rays several times with the INTEGRAL satellite, during the monitoring of the Galactic plane, with an unprecedented exposure time. We analysed all available INTEGRA...
متن کاملDiscovery of the X-ray Burster Sax J1752.3–3138
During a 50 ks monitoring observation of the Galactic bulge performed in September 1999 by the Wide Field Cameras on board the BeppoSAX satellite, an X-ray burst was detected from a sky position ∼ 3 • off the Galactic centre. No previously known X-ray sources are located within the position error circle of the observed burst. The new burster, SAX J1752.3−3138, did not show any persistent emissi...
متن کاملBeppoSAX and ASCA observations of the Galactic Bulge source 1 E 1743 . 1 - 2843
We report the results of BeppoSAX and ASCA observations of the X–ray source 1E 1743.1–2843, located in the region of the galactic center, performed between 1993 and 1998. Observations spanning almost twenty years show that 1E 1743.1–2843 is a persistent X–ray source, most likely powered by accretion onto a compact galactic object. The absence of periodic pulsations and the relatively soft X–ray...
متن کاملX-ray Transients in the Galactic Center Region
In the last 15 years, 6 dedicated observation programs were carried out to monitor ∼ 20 o around the galactic center for transient activity above a few keV. Transient activity from low-mass X-ray binaries shows a strong preference for this field. Two programs are currently active, with the Wide Field Cameras on BeppoSAX and the Proportional Counter Array on RXTE. The coverage of these programs ...
