cds-question@unistra.frpeculiar-variable-starsearly-type-starsvisible-astronomymedium-band-photometryDifferential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for four magnetic chemically peculiar stars. Comparison with uvby photometry of Pedersen & Thomsen for HD 37776 yields an improved period of 1.538675 days. New periods of 15.0305 days and 18.065 days are found for the sharp-lined stars HR 2258 and HR 6958, respectively, rather than one of their aliases. For HR 6958 each color shows a slightly different time of maximum. Comparison of the four color photometry of 108 Aqr taken during the fall of 1995 which well covers the period shows the presence of a secondary minimum near primary maximum in u, v, and b. Comparison with published photometry indicates indicates that subtle changes in the shapes of the light curves have occurred suggesting that this star might be precessing.1997A&AS..125...65Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/125/65CatalogResearchIsServedByTAP 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 : HD11187, HD14940, HD15144, 20 Eri & HR8933 (Adelman+, 1995)J/A+AS/122/249 : HD 32633, 25 Sex, HR 7224 & HD 200311 (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/133/197 : 33 Tau, HD 50169 and HR 7786 (Adelman+ 1998)J/A+AS/134/53 : HD 15980, HR 1094, 33 Gem and HD 115708 (Adelman+ 1999)J/A+AS/136/111 : HD 35298, 19 Lyr, HD 192678 and HR 8216 (Adelman 1999)J/A+AS/136/379 : 45 Leo, HR 4330, 49 Her and HR 6718 (Adelman+ 1999)J/A+AS/146/13 : 20 Eri, HR 1297, 12 CMa, and HD 134214 (Adelman, 2000)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/125/65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/125/65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/125/65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/125/65https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/125/65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/125/65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/125/65/table2uvby Photometry for HD 37776recnoRecord number assigned by the VizieR team.
