Abstract:
Differential Stroemgren uvby observations from the Four College
Automated Photoelectric Telescope are presented for the mCP stars
HD 35298, 19 Lyr, HD 192678, and HR 8216. The period for HD 35298 of
1.85457 days is a revision of North's value while that for 19 Lyr of
7.0980 days is alias of that found by Winzer. HD 192678 is found to be
a small amplitude photometric variable with the 6.4186 day period
proposed by Leroy from polarization measurements. For HR 8216,
observations taken between 1995 and 1998 confirm that the star has
remained constant at least since 1990.
