J/A+AS/134/53       uvby photometry of 4 CP stars     (Adelman 1999)

uvby Photometry of the chemically peculiar stars. HD 15980, HR 1094, 33 Gem, and HD 115708 Adelman S.J. <Astron. Astrophys. Suppl. Ser. 134, 53 (1999)> =1999A&AS..134...53A (SIMBAD/NED BibCode)
ADC_Keywords: Photometry, uvby ; Stars, variable Keywords: stars: individual: HD 15980, HR 1094, 33 Gem, HD 115708 - stars: chemically peculiar Abstract: Differential Stroemgren uvby photometry obtained with the Four College Automated Photoelectric Telescope shows that the hot HgMn star 33 Gem is photometrically constant. The Si star HD 15980 is found to be a variable whose period is significantly greater than 2 years. The unusual magnetic chemically peculiar Co star HR 1094 is discovered to be a low amplitude photometric variable with the magnetic field period of Hill & Blake (1996MNRAS.278..183H), 2.9761 days. The ephemeris for the magnetic chemically peculiar star HD 115708 of Wade et al. (1996A&A...307..500W) is confirmed with the error in its period of 5.07622 days being greatly reduced. The u, v, b, and y light curves for both HR 1094 and HD 115708 exhibit differences which indicate complex elemental photospheric abundance distributions.
