cds-question@unistra.frpeculiar-variable-starsAbout 10% of upper main-sequence stars are characterized by the presence of chemical peculiarities, often found together with a structured magnetic field. The atmospheres of most of those chemically peculiar stars present surface spots, leading to photometric variability caused by rotational modulation. The study of the light curves of those stars therefore permits a precise measurement of their rotational period, which is important to study stellar evolution and to plan further detailed observations. We analysed the light curves of 1028 chemically peculiar stars obtained with the STEREO spacecraft. We present here the results obtained for the 337 magnetic chemically peculiar stars in our sample.2012MNRAS.420..757Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/420/757CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/260 : General Catalogue of Ap and Am stars (Renson+ 2009)J/MNRAS/429/119 : STEREO non-magnetic chemically peculiar stars (Paunzen+ 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/420/757https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/420/757http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/420/757https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/420/757https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/420/757http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/420/757GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/420/757/table1 (Basic properties of the CP2 and CP4 stars identified as constant or for which the quality of the data prevented the detection of any variability)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/420/757/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/420/757/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/420/757/table1?GETtext/xml+votable180.050000true3.51693-0.033370.005555555555555556Cone search capability for table J/MNRAS/420/757/table2 (Basic properties of the CP2 and CP4 stars identified as constant or probably constant after the individualised analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/420/757/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/420/757/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/420/757/table2?GETtext/xml+votable180.050000true0.45603-3.02750.005555555555555556Cone search capability for table J/MNRAS/420/757/table3 (Properties of the CP2 and CP4 stars identified as photometrically variable)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/420/757/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/420/757/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/420/757/table3?GETtext/xml+votable180.050000true1.9338-2.548680.0055555555555555565/6095 6112-6113 6117 6121 6123 6126 6/263 351 375 389 421 429 463 465 472 481 510 666 812 842 1044 1060 1125 1169 1182 1284-1285 1287 1296 4251 4263 4672 4711 4775 4860 4890 6154 6185 6229 6661 17323 17395 17397 17888 18086 18096 18134 18162 18193 18273 18315 18352 18455 18510 18566 18615 18619 18797 18825 19513 19611 19733 19778 23679 23763 23769 23782 23862 23866 23871 23911 23922 23934 23937 23945 23959 23980 23997 24005 24077 24092 24094 24102 24108 24171 24189-24191 24274 24287 24332-24333 24335 24338-24339 24344-24346 24350 24353 24355-24356 24358 24360-24361 24363 24367 24369-24370 24373-24375 24377-24379 24404 24415 24418 24426 24457 24459-24461 24463 24465-24467 24472-24473 24475 24477-24479 24481 24483 24489-24491 24499 24502-24503 24512 24514 24517-24518 24520 24522-24523 24544 24925 25079 25420 25450 25649 25686 25762 26145 26299 26315 26353 26977 27010 27021 27102 27120 27130 27541 28192 30735 30761 42813 42861 42866 42876 42899 42903 42934 42943 42947 42949 42953 42959 42961 42966-42968 42975 42977 42979 42984 42987 44258 44293 44307 44310 44317 44321 44363 44371 44378 44386 44441 44451 44468 44481 44499 44651 44764 44825 44844 44880 48582 48587 48601 48635-48636 48641 48702 48755 48790-48791 48888 48896 48998 49030 49085 49123https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/420/757?format=asciidefaultJ/MNRAS/420/757/table1Basic properties of the CP2 and CP4 stars identified as constant or for which the quality of the data prevented the detection of any variabilityrecnoRecord number assigned by the VizieR team.
