Abstract:
Differential Stroemgren uvby photometric observations from the Four
College Automated Photoelectric Telescope are presented for four
Chemically Peculiar stars of the upper main sequence: the HgMn star
binary AR Aurigae and the magnetic stars 3 Hydrae, 49 Cancri, and
BX Bootis. AR Aurigae shows little variability except during the
primary and secondary eclipses. The 11.305 day period of Maitzen et
al. for 3 Hya is confirmed. A new period of 7.0501 days is found for
49 Cancri while a slightly refined period of 2.88756 days is derived
for BX Boo.
