cds-question@unistra.frvariable-starspeculiar-variable-starsstellar-spectral-typesThe magnetic Ap or CP2 stars are natural atomic and magnetic laboratories. Strictly periodic changes are observed in the spectra and brightness of these stars, which allow the derivation of rotational periods. Related to this group of objects are the He-weak (CP4) and He-rich stars, some of which also undergo brightness changes due to rotational modulation. Increasing the sample size of known rotational periods among CP2/4 stars is important and will contribute to our understanding of these objects and their evolution in time. We have compiled an extensive target list of CP2/4 stars from the General Catalog of Ap, HgMn, and Am stars, including several early-type (spectral types B/A) variables of undetermined type from the International Variable Star Index. We investigated our sample stars using publicly available observations from the ASAS-3 archive. Our previous efforts in this respect led to the discovery of 323 variable stars. Using a refined analysis approach, we were able to identify another 360 stars exhibiting photometric variability in ASAS-3 data. Summary data, folded light curves and, if available, information from the literature are presented for our final sample, which is composed of 334 bona-fide {alpha}^2^ Canum Venaticorum (ACV) variables, 23 ACV candidates, and 3 eclipsing binary systems. Interesting and unusual objects are discussed in detail. In particular, we call attention to HD66051 (V414 Pup), which is an eclipsing binary system showing obvious rotational modulation of the light curve due to the presence of an ACV variable in the system.2016AJ....152..104Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/104CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2014)B/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2013)III/260 : General Catalogue of Ap and Am stars (Renson+ 2009)I/280 : All-sky Compiled Catalogue of 2.5 million stars (Kharchenko+ 2009)II/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2002-2005)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/259 : The Tycho-2 Catalogue (Hog+ 2000)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)II/97 : ANS UV Catalogue of Point Sources (Wesselius+ 1982)J/A+A/581/A138 : Photometric variability in CP stars (Bernhard+, 2015)J/AN/336/590 : Bochum Galactic Disk Survey: II (Hackstein+, 2015)J/MNRAS/427/2917 : Classification of Hipparcos variables (Rimoldini+, 2012)J/MNRAS/420/757 : STEREO magnetic chemically peculiar stars (Wraight+, 2012)J/A+A/525/A16 : Light curves of CP stars in open clusters (Paunzen+, 2011)J/other/IBVS/5480 : Elements for 80 eclipsing binaries (Otero, 2003)J/MNRAS/331/45 : New periodic variables (Koen+, 2002)http://www.astrouw.edu.pl/asas/ : ASAS websitehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/152/104https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/152/104http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/152/104https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/152/104https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/152/104http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/152/104GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/152/104/table2 (Essential data for the stars identified as photometrically variable Chemically Peculiar (CP) stars or candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/152/104/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/152/104/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/152/104/table2?GETtext/xml+votable180.050000true8.1836667-13.48708330.0055555555555555566/659 12382 12519 12859 12953 12993 13186 14362 14375 16789 16876 17546 20535 20764 20797 20828 20862 20896 20954 20955 20960 20983 20985 21298 21366 21447 21510 21549 21550 21561 21649 21663 21695 22018 22088 22148 22176 22227 22254 22415 22879 23273 23347 23379 23589 23590 23623 23665 24335 24350 24448 24722 26285 28673 28678 28689 28702 28721 28740 28755 28773 28802 28867 28889 28893 28929 28955 28967 29028 29051 29081 29084 29085 29101 29112 29195 29337 29443 29463 29613 29858 30209 30439 30465 30563 30576 30645 30678 30697 30712 31069 31260 31749 31790 31812 32885 33047 33189 33305 33566 33976 36473 36919 36984 37063 37069 37139 37177 37187 37201 37335 37351 37356 37361 37368 37369 37464 37485 37502 37566 37585 37592 37634 37650 37715 37725 37729 37739 37773 37783 37803 37826 37874 37893 37903 37914 37934 37936 37937 37948 37968 38016 38018 38035 38049 38085 38101 38113 38145 38657 38662 38861 39117 39141 39169 39175 39181 39182 39196 39216 39218 39219 39220 39225 39240 39268 39274 39285 39294 39341 39345 39365 39372 39613 39622 39704 39713 39717 39729 39741 39784 39796 39817 39866 39894 39903 39910 39942 39962 40120 40128 40168 40459 40496 40505 40521 40552 40623 40634 40640 40668 40686 40754 40914 41064 41067 41144 41153 41154 41165 41172 41182 41192 41197 41198 41202 41221 41262 41396 41405 41406 41409 41422 41424 41425 41429 41430 41444 41455 41477 41490 41497 41526 41542 41558 41566 41567 41584 41603 41637 41643 41665 41666 41673 41679 41680 41684 41706 41715 41730 41735 41751 41767 41773 41774 41781 41795 41802 41803 41804 41826 41833 41843 41848 41863 41868 41873 41875 41879 41882 41898 41901 41991 42013 42015 42026 42035 42042 42062 42080 42088 42098 42108 42137 42138 42144 42147 42155 42170 42172 42204 42222 42235 42274 42283 42289 42365 42410 42510 42520 42537 42600 42630 42651 42663 42690 42804 42826 42871 42943 42947 42968 43025 43032 43049 43052 43053 43058 43066 43083 43089 43096 43097 43146 43155 43175 43218 43219 43282 43287 43301 43302 43308 43314 43429 43751 44738 45222 47033 47147 47153 47262 47329 47703 47783 47784 47799 47847 48034 48321https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/152/104?format=asciidefaultJ/AJ/152/104/table2Essential data for the stars identified as photometrically variable Chemically Peculiar (CP) stars or candidatesSimbadNameSimbad column added by the CDSmeta.idcharSpTSpectral type (6)src.spTypecharrecnoRecord number assigned by the VizieR team.
