J/A+A/357/548       ubvy Photometry of magnetic CP stars     (Adelman+, 2000)

uvby Photometry of the magnetic CP stars HD 36668, 36 Lyncis, HD 86952, and HR 8861 Adelman S.J. <Astron. Astrophys. 357, 548 (2000)> =2000A&A...357..548A
ADC_Keywords: Stars, peculiar ; Photometry, uvby Keywords: stars: individual: HD 36668, 36 Lyn, HR 1297, HR 8861 - stars: chemically peculiar Abstract: Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope (FCAPT) are presented for the magnetic CP stars HD 36668, 36 Lyn, HD 86592, and HR 8861. Using the FCAPT values, North's period for HD 36668 is refined to 2.11884 days. The 3.834 day period of Shore et al. (1990ApJ...348..242S) for 36 Lyn, which was found from magnetic field measurements, is confirmed by photometry. The FCAPT observations also support the 2.8867 day period of Babel & North (1997A&A...325..195B) for HD 86592, demonstrate that this star is a large amplitude variable in v (0.13 mag), and show that y varies crudely out of phase from u, v, and b which are in phase with one another. The variability of HR 8861 appears to be correlated with the meridional passages of regions of Si over- and underabundance as found by Piskunov et al.
