Faint X-ray Sources in the Globular Cluster Terzan 5
We report our analysis of a Chandra X-ray observation of the rich globular cluster Terzan 5, in which we detect 50 sources to a limiting 1.0-6 keV X-ray luminosity of 3 × 10 ergs s within the half-mass radius of the cluster. Thirty-three of these have LX > 10 32 ergs s, the largest number yet seen in any globular cluster. In addition to the quiescent low-mass X-ray binary (LMXB, identified by W...
متن کاملX-ray sources in globular clusters
The twelve bright (Lx > 10 36 erg s) X-ray sources in the globular clusters have lower luminosities than the brightest sources in the bulge of our galaxy. The dim (Lx < 10 35 erg s) X-ray sources in globular clusters reach higher luminosities than the cataclysmic variables in the disk of our galaxy. The first difference is a statistical fluke, as comparison with M 31 indicates. The second diffe...
متن کاملFaint X - ray sources in globular clusters in the XMM - Newton and Chandra era
X-ray imaging and spectroscopy can be used to probe the binary content of globular clusters. Binaries are thought to play a key role in the dynamical evolution of the clusters by serving as an internal source of energy which counters the tendency of their cores to collapse. Various kinds of binaries are found in clusters in X-rays, including BY Dra or RS CVn systems, Cataclysmic Variables and l...
متن کاملMultiple and variable X - ray sources in the globular clusters
We detect stars from the Hipparcos and Tycho Catalogues in the field of view of observations with the ROSAT HRI of three globular clusters. We use the positions of these stars to reduce the systematic error in the positions of X-ray sources in the clusters to ∼ 2′′ for ω Cen and NGC 6752, and 1′′ for NGC 6397. We detect three X-ray sources in the core of ω Cen, and four in the core of NGC 6752;...
متن کاملGalactic Globular Clusters with Luminous X-Ray Binaries
Luminous X-ray binaries (>10 erg s, LMXBs) have a neutron star or black hole primary, and in globular clusters, most of these close binaries are expected to be have evolved from wider binaries through dynamical interactions with other stars. We sought to find a predictor of this formation rate that is representative of the initial properties of globular clusters rather than of the highly evolve...
