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 new sample of broad-absorption-line quasars exhibiting the ghost of lyman alpha
M. North, C. Knigge, M. Goad
We have searched the broad-absorption-line quasar (BAL QSO) sample presented by Reichard et al. for objects exhibiting the so-called `ghost of Lyman alpha'. This ghost manifests as…
On the Origin of the Absorption Features in SS433
A. D. Barnes, J. Casares, P. A. Charles +4
We present high-resolution optical spectroscopy of the X-ray binary system SS433, obtained over a wide range of orbital phases. The spectra display numerous weak absorption feature…
An ultracompact X-ray binary in the globular cluster M15 (NGC7078)
A. Dieball, C. Knigge, D. R. Zurek +5
We have used the Advanced Camera for Surveys on board the Hubble Space Telescope to image the core of the globular cluster M15 in the far-ultraviolet (FUV) waveband. Based on these…
Ultraviolet studies of interacting binaries
B. T. Gaensicke, D. de Martino, T. R. Marsh +4
Interacting Binaries consist of a variety of stellar objects in different stages of evolution and those containing accreting compact objects still represent a major challenge to ou…
Five WC9 stars discovered in the AAO/UKST H-alpha Survey
E. C. Hopewell, M. J. Barlow, J. E. Drew +7
We report the discovery of 5 massive Wolf-Rayet (WR) stars resulting from a programme of follow-up spectroscopy of candidate emission line stars in the AAO/UKST Southern Galactic P…
