Identification of the X - ray Burster X 1746 - 370 in the Globular Cluster NGC 6441
We find convincing observational evidence to confirm the optical identification of the X-ray burster X1746-370 located in the globular cluster NGC6441. Chandra/HRC-I imaging yields a much improved X-ray position for the source, which we show to be fully consistent with our rederived position of a UV-excess star, U1, in the same astrometric reference frame. In addition, the smaller Chandra X-ray...
متن کاملGlobular cluster x-ray sources.
Globular clusters and x-ray astronomy have a long and fruitful history. Uhuru and OSO-7 revealed highly luminous (> 10(36) ergs(-1)) x-ray sources in globular clusters, and Einstein and ROSAT revealed a larger population of low-luminosity (< 10(33) ergs(-1)) x-ray sources. It was realized early on that the high-luminosity sources were low-mass x-ray binaries in outburst and that they were order...
متن کاملTime - Resolved Ultraviolet Observations of the Globular Cluster X - ray Source in NGC 6624 : The Shortest Known Period Binary System
Using the Faint Object Spectrograph (FOS) aboard the Hubble Space Telescope, we have obtained the first time-resolved spectra of the King et al. ultraviolet-bright counterpart to the 11-minute binary X-ray source in the core of the globular cluster NGC6624. This object cannot be readily observed in the visible, even from HST, due to a much brighter star superposed < 0.1 distant. Our FOS data sh...
