Abstract:
Differential Stroemgren uvby observations from the Four College
Automated Photoelectric Telescope (FCAPT) are presented for the mCP
stars HD 142070, HR 6967, and HR 8434 and the CP star HR 5341. The
latter star is found to be constant. Improved periods were derived for
HD 142070, 3.37189d, HR 6967, 3.91227d, and HR 8434, 1.43237d. Further
observations of HD 142070 are needed to phase the magnetic data with
the photometry, of HR 6967 to settle minor discrepancies between y and
scaled Geneva V photometry, and of HR 8434 to resolve small
discrepancies between two uvby photometric data sets.
