In order to decide whether the seeing conditions at SAAO/Sutherland justify the erection of a 3.5 m telescope and also to compare Sutherland with the Gamsberg/Namibia site, a seeing campaign covering 15 months has been carried out. For direct compari

This paper discusses the first all-sky surveys of cosmic extreme ultra-violet and soft X-ray sources, discovered by ROSAT. Details of the surveys are presented, with comparisons made to previous selected surveys in the X-ray regime. The subsequent op

As first pointed out by Warner (1985), the overall properties of CP Pup and V1500 Cyg are very similar: both were very fast, very large amplitude novae with ~ 0.3 mag photometric humps at roughly the orbital period. Neither variation is strictly peri

The internal absorption in spiral galaxies is investigated statistically using data in the UV, optical and near-infrared wavelength regions. It is shown that a three-component model of the galaxy structure leads to absorption values which are consist

L'analyse des observations photometriques et des vitesses radiales derivees des observations spectroscopiques de l'ex-nova CP Pup fournit une periode de modulation en desaccord avec des donnees anterieures, suggerant la presence de plus d'une periodi

Spectral observations obtained soon after the 1987 brightening of U Sco support a thermonuclear runaway model for outbursts of this object. Spectra later in the decline are, however, more characteristic of a hot accretion disc. These observations are
