Optical properties of High-Mass X-ray Binaries (HMXB) in the Small Magellanic Cloud
M. J. Coe, R. H. D. Corbet, K. E. McGowan +6
The SMC represents an exciting opportunity to observe the direct results of tidal interactions on star birth. One of the best indicators of recent star birth activity is the presen…
The Chandra Small Magellanic Cloud Wing Survey - the search for X-ray Binaries
K. E. McGowan, M. J. Coe, M. P. E. Schurch +6
We have detected 523 sources in a survey of the Small Magellanic Cloud (SMC) Wing with Chandra. By cross-correlating the X-ray data with optical and near-infrared catalogues we hav…
Optical Follow-up of New SMC Wing Be/X-ray Binaries
M. P. E. Schurch, M. J. Coe, K. E. McGowan +4
We investigate the optical counterparts of recently discovered Be/X-ray binaries in the Small Magellanic Cloud. In total four sources, SXP101, SXP700, SXP348 and SXP65.8 were detec…
The metallicity extremes of the Sagittarius dSph using SALT spectroscopy of PNe
A. Kniazev, A. Zijlstra, E. Grebel +10
In this work we present the first spectroscopic results obtained with the Southern African Large Telescope (SALT) telescope during its perfomance-verification phase. We find that t…
The polar ring galaxy AM1934-563 revisited
N. Brosch, A. Kniazev, D. Buckley +8
We report long-slit spectroscopic observations of the dust-lane polar-ring galaxy AM1934-563 obtained with the Southern African Large Telescope (SALT) during its performance-verifi…
Outbursts of EX Hydrae Revisited
N. Mhlahlo, D. A. H. Buckley, V. Dhillon +3
We present optical spectroscopy of EX Hya during its 1991 outburst. This outburst is characterised by strong irradiation of the front face of the secondary star by the white dwarf,…
