Determining the extragalactic extinction law with SALT

Ido Finkelman, Noah Brosch, Alexei Y. Kniazev +7

We present CCD imaging observations of early-type galaxies with dark lanes obtained with the Southern African Large Telescope (SALT) during its performance-verification phase. We d…

The space density of cataclysmic variables: constraints from the ROSAT North Ecliptic Pole Survey

M. L. Pretorius, C. Knigge, D. O'Donoghue +3

We use the ROSAT North Ecliptic Pole (NEP) survey to construct a small, but purely X-ray flux-limited sample of cataclysmic variable stars (CVs). The sample includes only 4 systems…

The mass and radius of the M-dwarf in the short period eclipsing binary RR Caeli

P. F. L. Maxted, D. O'Donoghue, L. Morales-Rueda +1

We present new photometry and spectroscopy of the eclipsing white dwarf - M-dwarf binary star RR Cae. We use timings of the primary eclipse from white-light photo-electric photomet…

SDSS J160043.6+074802.9: a very rapid sdO pulsator

P. A. Woudt, D. Kilkenny, E. Zietsman +12

We report the serendipitous discovery of the Sloan Digital Sky Survey star, SDSS J160043.6+074802.9 to be a very rapid pulsator. The variation is dominated by a frequency near 8380…

Simultaneous X-ray/optical observations of GX 9+9 (4U 1728-16)

A. K. H. Kong, P. A. Charles, L. Homer +2

We report on the results of the first simultaneous X-ray (RXTE) and optical (SAAO) observations of the luminous low mass X-ray binary (LMXB) GX 9+9 in 1999 August. The high-speed o…

XMM Spectroscopy of the Transient Supersoft Source RX J0513.9-6951: probing the dynamic white dwarf photosphere

Katherine E. McGowan, Phil A. Charles, Alexander J. Blustin +3

The highly luminous (> 10^37 erg s^-1) supersoft X-ray sources (SSS) are believed to be Eddington limited accreting white dwarfs undergoing surface hydrogen burning. The current pa…
