Three Additional Quiescent Low-Mass X-ray Binary Candidates in 47 Tucanae
C. O. Heinke, J. E. Grindlay, P. D. Edmonds
We identify through their X-ray spectra one certain (W37) and two probable (W17 and X4) quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars in a long Chandra X-ray…
X-ray variability during the quiescent state of the neutron-star X-ray transient in the globular cluster NGC 6440
Edward M. Cackett, Rudy Wijnands, Craig O. Heinke +6
The globular cluster NGC 6440 is known to harbor a bright neutron-star X-ray transient. We observed the globular cluster with Chandra on two occasions when the bright transient was…
Discovery of an Optical Counterpart to the Supersoft X-ray Source in the Globular Cluster M3
Peter D. Edmonds, Peter Kahabka, Craig O. Heinke
We report the detection, with HST, of an optical counterpart to the transient supersoft X-ray source 1E 1339.8+2837, in the globular cluster M3. The counterpart is found near the f…
