The hard quiescent spectrum of the neutron-star X-ray transient EXO 1745-248 in the globular cluster Terzan 5
Rudy Wijnands, Craig O. Heinke, David Pooley +5
We present a Chandra observation of the globular cluster Terzan 5 during times when the neutron-star X-ray transient EXO 1745-248 located in this cluster was in its quiescent state…
An Extensive Census of HST Counterparts to Chandra X-ray Sources in the Globular Cluster 47 Tucanae. II. Time Series and Analysis
Peter D. Edmonds, Ronald L. Gilliland, Craig O. Heinke +1
We report time series and variability information for the optical identifications of X-ray sources in 47 Tuc reported in Paper I. The eight CVs with secure orbital periods have fai…
An Extensive Census of HST Counterparts to Chandra X-ray Sources in the Globular Cluster 47 Tucanae. I. Astrometry and Photometry
Peter D. Edmonds, Ronald L. Gilliland, Craig O. Heinke +1
We report the largest number of optical identifications of X-ray sources yet obtained in a single globular cluster. Using deep Chandra/ACIS-I imaging and extensive HST studies with…
Analysis of the Quiescent Low-Mass X-ray Binary Population in Galactic Globular Clusters
C. O. Heinke, J. E. Grindlay, P. M. Lugger +4
Quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars have been identified in several globular clusters using Chandra or XMM X-ray observations, using their soft ther…
A Chandra X-ray Study of the Globular Cluster M80
C. O. Heinke, J. E. Grindlay, P. D. Edmonds +4
We report our analysis of a Chandra X-ray observation of the rich globular cluster M80, in which we detect some 19 sources to a limiting 0.5-2.5 keV X-ray luminosity of 7*10^30 erg…
A Chandra Study of the Dense Globular Cluster Terzan 5
C. O. Heinke, P. D. Edmonds, J. E. Grindlay +3
We report a Chandra ACIS-I observation of the dense globular cluster Terzan 5. The previously known transient low-mass x-ray binary (LMXB) EXO 1745-248 in the cluster entered a rar…
