cds-question@unistra.frglobular-star-clustersccd-photometrypeculiar-variable-starsWithin the sample of six young open clusters (NGC 1502, NGC 3105, Stock 16, NGC 6268, NGC 7235 and NGC 7510) we have investigated 1753 objects using the narrow band, three filter Delta a photometric system resulting in the detection of eleven bona-fide magnetic chemically peculiar (CP) stars and five Be or metal-weak stars. The results for the distant cluster NGC 3105 is most important because of the still unknown influence of the global metallicity gradient of the Milky Way. These findings confirms that CP stars are present in open clusters of very young ages (logt>=6.90) at galactocentric distances up to 11.4kpc. For all programme clusters the age, reddening and distance modulus were derived using the corresponding isochrones. Some additional variable stars within Stock 16 could be identified by comparing different photometric studies.2005A&A...443..157Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/443/157CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toGCPD/75 : the Maitzen photometric system (1976A&A....51..223M)J/A+A/371/L5 : CCD {Delta}a-photometry of NGC 1866 (Maitzen+, 2001)J/A+A/373/153 : CCD {Delta}a-photometry of 5 open clusters (Paunzen+, 2001)J/A+A/385/867 : CCD {Delta}a-photometry of 5 open clusters (Paunzen+, 2002)J/A+A/395/823 : CCD {Delta}a-photometry of 5 open clusters (Paunzen+, 2002)J/A+A/412/721 : CCD {Delta}a-photometry of 5 open clusters (Paunzen+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/443/157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/443/157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/443/157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/443/157https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/443/157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/443/157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/443/157/table8 (Observed program stars of NGC 7235)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/443/157/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/443/157/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/443/157/table8?GETtext/xml+votable180.050000true333.198583157.26384080.005555555555555556Cone search capability for table J/A+A/443/157/table4 (Observed program stars of NGC 1502)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/443/157/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/443/157/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/443/157/table4?GETtext/xml+votable180.050000true61.978510662.33816890.005555555555555556Cone search capability for table J/A+A/443/157/table5 (Observed program stars of NGC 3105)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/443/157/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/443/157/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/443/157/table5?GETtext/xml+votable180.050000true150.3709492-54.81398060.005555555555555556Cone search capability for table J/A+A/443/157/table6 (Observed program stars of Stock 16)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/443/157/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/443/157/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/443/157/table6?GETtext/xml+votable180.050000true199.7187314-62.45597170.005555555555555556Cone search capability for table J/A+A/443/157/table7 (Observed program stars of NGC 6268)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/443/157/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/443/157/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/443/157/table7?GETtext/xml+votable180.050000true255.5847497-39.72270580.005555555555555556Cone search capability for table J/A+A/443/157/table9 (Observed program stars of NGC 7510)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/443/157/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/443/157/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/443/157/table9?GETtext/xml+votable180.050000true347.729919460.55406440.0055555555555555566/3384 14310 15620 15622 37375 41698 42398-42399https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/443/157?format=asciiOpticaldefaultJ/A+A/443/157/table8Observed program stars of NGC 7235recnoRecord number assigned by the VizieR team.
