cds-question@unistra.frvisible-astronomymedium-band-photometryvariable-starsDifferential 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.1999A&AS..134...53Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/134/53CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/103/1 : 63 And, HD 192913, HR 8240 & 108 Aqr (Adelman+ 1994)J/A+AS/106/333 : Alpha And, HD 184905, HR 8216 & HR 8434 (Adelman+ 1994)J/A+AS/114/253 : HD 11187, HD 14940, HD 15144, 20 Eri, HR 8933 (Adelman+ 1995)J/A+AS/122/249 : HD 32633, 25 Sex, HR 7224 & HD 200311 (Adelman, 1997)J/A+AS/125/65 : HD 37776, HR 2258, HR 6958 & 108 Aqr (Adelman, 1997)J/PASP/109/9 : HR 1643, Theta Aur, 49 Cam, and HR 3724 (Adelman 1997)J/A+AS/125/497 : Theta Vir and 109 Vir (Adelman 1997)J/A+AS/128/245 : AR Aur, 3 Hya, 49 Cnc & BX Boo (Adelman 1997)J/A+AS/133/197 : 33 Tau, HD 50169 and HR 7786 (Adelman+ 1998)J/A+AS/136/379 : 45 Leo, HR 4330, 49 Her and HR 6718 (Adelman+ 1999)J/A+A/368/225 : HR 5341, HD 142070, HR 6967 & HR 8434 (Adelman, 2001)J/A+A/390/1023 : HR 194, HD 32966, HD 171782, and HR 7911 (Adelman+, 2002)J/A+A/401/357 : 60 Tau, HR 1528, HR 8216, HR 8770 (Adelman+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/134/53https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/134/53http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/134/53https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/134/53https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/134/53http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/134/53GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/134/53/table3Photometry of HD 15980recnoRecord number assigned by the VizieR team.
