J/A+AS/133/197   uvby Photometry of 33 Tau, HD 50169 and HR 7786 (Adelman+ 1998)

uvby photometry of 33 Tauri, HD 50169, and HR 7786 and an assessment of FCAPT comparison stars Adelman S.J., Pi C.-L.M., Rayle K. <Astron. Astrophys. Suppl. Ser. 133, 197 (1998)> =1998A&AS..133..197A (SIMBAD/NED BibCode)
ADC_Keywords: Photometry, uvby ; Stars, peculiar Keywords: stars: individual: 33 Tauri, HD 50169, HR 7786, HR 7721 - stars: chemically peculiar Abstract: Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for the ellipsoidal variable 33 Tauri, and the magnetic Chemically Peculiar stars HD 50169 and HR 7786. We confirm that Hube's period of 2.975272 days for 33 Tau is correct. HD 50169 is a constant MCP star. HR 7786 is a large amplitude class member confirming Winzer's discovery, but its period is 8.5297 days. Its comparison star, HR 7721, a spectroscopic binary B7 V star, is variable with an amplitude of order 0.1mag, but of indeterminant period. In addition Hipparcos photometry of the comparison and check stars for early type stars whose photometry is being obtained with the FCAPT is reviewed to ascertain the stability of these stars.
