CCD PHOTOMETRY OF VARIABLE-STARS IN THE MAGELLANIC CLOUDS .4. THE ECLIPSING BINARY HV-1761 AND NEARBY FIELD VARIABLES

B, V and I CCD photometry is presented for the SMC eclipsing binary HV 1761 and five other variable stars in the same field. HV 1761 is deta ched and seen close to edge-on. Any orbital eccentricity is slight. Th e system plausibly comprises early B stars differing by no more than a pproximately 30 per cent in radius and separated by about three times their mean radius. HV 1787 and 12151 are known Cepheid variables, with light curves very similar to those of Galactic Cepheids. HV 12153 is found to have a 1.07-d period and to be consistent with the first-over tone pulsation period-luminosity relation for anomalous Cepheids. Two newly discovered variables 0.5 mag brighter than HV 1761, but of simil ar colour, are possibly a slightly eccentric 1.5-d eclipsing binary an d a Be star.
