Intensive photometry of southern Wolf-Rayet stars.
Abstract
Results of an intensive photometric campaign on 17 of the brightest southern Wolf-Rayet stars are presented. The detection of multiperiodicity in two stars, HD 50896 and HD 96548, is reported. It is likely that these periodicities are not coherent but are manifestations of the quasi-periodic variations seen in a few WR stars. A good example of these variations is given by HD 86161. A new eclipsing binary, HD 92740, has been discovered; other stars show periodic variations which can be explained by phase-dependent scattering of the secondary light as it traverses the Wolf-Rayet wind. An important conclusion of this study is that not a single example was found of short-period variations which can be attributed to pulsation.
