WFCAM Survey of M31 Globular Clusters: Low Mass X-ray Binaries
Mark B. Peacock, Thomas J. Maccarone, Christopher Z. Waters +4
We investigate the relationship between Low Mass X-ray Binaries (LMXBs) and globular clusters (GCs) using UKIRT observations of M31 and existing Chandra, XMM-Newton, and ROSAT cata…
Combined Chandra, XMM-Newton and Hubble Space Telescope observations of the Galactic globular cluster NGC 2808
M. Servillat, A. Dieball, N. A. Webb +6
Using new Chandra X-ray observations and existing XMM-Newton X-ray and Hubble far ultraviolet observations, we aim to detect and identify the faint X-ray sources belonging to the G…
Stellar Exotica in 47 Tucanae
Christian Knigge, Andrea Dieball, Jesus Maiz Apellaniz +3
We present far-UV spectroscopy obtained with HST for 48 blue objects in the core of 47 Tuc. Based on their position in a FUV-optical colour-magnitude diagram, these were expected t…
Unveiling the core of the Globular Cluster M15 in the Ultraviolet
A. Dieball, C. Knigge, D. R. Zurek +4
We have obtained deep far- (FUV) and near-ultraviolet (NUV) images of the inner region of the dense globular cluster M15 with the Advanced Camera for Surveys on board the Hubble Sp…
A Blue Straggler Binary System with at least Three Progenitors in the Core of a Globular Cluster?
C. Knigge, R. L. Gilliland, A. Dieball +3
We show that the X-ray source W31 in the core of the globular cluster 47 Tucanae is physically associated with the bright blue straggler BSS-7. The two sources are astrometrically…
A Spectroscopic Analysis of Blue Stragglers, Horizontal Branch and Turn-Off Stars in Four Globular Clusters
Orsola De Marco, Michael M. Shara, D. Zurek +4
We present a spectroscopic analysis of HST/STIS and FOS low- and intermediate-resolution spectroscopy of 55 stars (turn-off stars, horizontal branch stars and blue stragglers) in f…
