cds-question@unistra.frpeculiar-variable-starsvisible-astronomymedium-band-photometryDifferential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for four Chemically Peculiar stars of the upper main sequence: the HgMn star binary AR Aurigae and the magnetic stars 3 Hydrae, 49 Cancri, and BX Bootis. AR Aurigae shows little variability except during the primary and secondary eclipses. The 11.305 day period of Maitzen et al. for 3 Hya is confirmed. A new period of 7.0501 days is found for 49 Cancri while a slightly refined period of 2.88756 days is derived for BX Boo.1998A&AS..128..245Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/128/245CatalogResearchIsServedByTAP 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/133/197 : 33 Tau, HD 50169 and HR 7786 uvby Photometry (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/128/245https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/128/245http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/128/245https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/128/245https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/128/245http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/128/245GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/128/245/table2Photometry of AR AurrecnoRecord number assigned by the VizieR team.
