Abstract:
Differential Stroemgren uvby photometric observations from the 0.75-m
Four College Automated Photoelectric Telescope were obtained for three
metallic-line and three Mercury-Manganese stars. None were found to be
variable. These sharp-lined stars may not be the best tests for class
variability as their polar axes are pointed towards the earth. Each
presents essentially the same visible hemisphere as it rotates.
