The first star, which is a {delta} Scuti variable, was found not to change its mean magnitudes. HR 1528 is best described as constant. A decade of photometry of HR 8216 shows that its b and y values have changed by -0.016 and -0.010mag, respectively, over this time and now can be considered a photometric variable. For HR 8770 a period of 5.3923 days is derived with the photometric variability being generally in phase. The light curves also suggest possible surface abundance inhomogeneities.2003A&A...401..357Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/401/357CatalogResearchIsServedByTAP 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/111/41 : 56 Tauri, HD 111133, HD 126515 and HD 215441 (Adelman+ 1994)J/A+AS/114/253 : HD 11187, HD 14940, HD 15144, 20 Eri, HR 8933 (Adelman+ 1995)J/PASP/109/9 : HR 1643, Theta Aur, 49 Cam, and HR 3724 (Adelman 1997)J/A+AS/122/249 : HD32633, 25 Sex, HR 7224, and HD 200311 (Adelman, 1997)J/A+A/329/579 : uvby photometry of theta CrB (Fabregat+ 1998)J/A+AS/123/445 : uvby photometry of metallic + Hg-Mn stars (Adelman 1997)J/A+AS/125/65 : HD 37776, HR 2258, HR 6958 & 108 Aqu (Adelman, 1997)J/A+AS/125/497 : Theta Vir and 109 Vir uvby photometry (Adelman 1997)J/A+AS/128/245 : AR Aur, 3 Hya, 49 Cnc & BX Boo (Adelman 1997)J/A+A/333/952 : BVRI photometry of HR 1105 (Adelman 1998)J/A+AS/136/379 : 45 Leo, HR 4330, 47 Her & HR 6718 (Adelman+ 1999)J/A+AS/146/13 : 20 Eri, HR 1297, 12 CMa & 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 & HR 7911 (Adelman, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/401/357https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/401/357http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/401/357https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/401/357https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/401/357http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/401/357GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/401/357/table6Photometry of HR 8770recnoRecord number assigned by the VizieR team.
