Intensive photometry of southern Wolf-Rayet stars
Results of an intensive photometric campaign on 17 of the brightestsouthern Wolf-Rayet stars are presented. The detection ofmultiperiodicity in two stars, HD 50896 and HD 96548, is reported. It islikely that these periodicities are not coherent but are manifestationsof the quasi-periodic variations seen in a few WR stars. A good exampleof these variations is given by HD 86161. A new eclipsing binary, HD92740, has been discovered; other stars show periodic variations whichcan be explained by phase-dependent scattering of the secondary light asit traverses the Wolf-Rayet wind. An important conclusion of this studyis that not a single example was found of short-period variations whichcan be attributed to pulsation.
