cds-question@unistra.frpeculiar-variable-starsmagnetic-fieldsThe dependence of the degree of anomaly of parameter Z of Geneva photometry (Z0=Z_CP_-Z_norm_) on the average surface magnetic field Bs is analyzed. The Z0 value is proportional to the degree of anomaly of chemical composition. It was found that Bs-->0 corresponds Z0-->-0.010/-0.015, i.e., part of CP stars are virtually devoid of magnetic field, but exhibit chemical anomalies. This effect may be due to selection whereby only objects with strong chemical anomalies are classified as CP stars, thereby producing a deficit of stars with relatively weak anomalies. Moreover, CP stars have other sources of stabilization of their atmospheres besides the magnetic field, e.g., slow rotation. Formulas relating Z0 to Bs are derived.2007AstBu..62..244Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/AstBu/62.244CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/AstBu/62.244https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/AstBu/62.244http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/AstBu/62.244https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/AstBu/62.244https://vizier.iucaa.in/viz-bin/votable?-source=J/other/AstBu/62.244http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/AstBu/62.244GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/AstBu/62.244/table2 (Parameters Z0, which characterizes the intensity of the {lambda}5200{AA} depression, and {Delta}X, which characterizes the degree of chemical anomalies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/62.244/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/62.244/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/62.244/table2?GETtext/xml+votable180.050000true25.585525368.04302530.005555555555555556Cone search capability for table J/other/AstBu/62.244/table3 (Data for deriving the Z0-Bs relation for Bs values determined from line splitting (in kG))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/62.244/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/62.244/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/62.244/table3?GETtext/xml+votable180.050000true7.119038932.43774420.005555555555555556Cone search capability for table J/other/AstBu/62.244/table4 (Data for deriving the Bs-Z0 relation with Bs determined from the relation Bs=(5.6+-0.6)(<Be>-(0.16+-0.12)))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/62.244/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/62.244/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/62.244/table4?GETtext/xml+votable180.050000true7.119038932.43774420.0055555555555555566/263 351 389 463 481 842 962 1125 1164 1287 1313 1521 1697 1700 1763 2411 2490 2527 2682 2746 2817-2818 3030 3100 3266 3314 3678 3694 3705 4206 4251 4890 5501 5805 6229 6497 6759 6822 7487 7527 7705 7734 7917 8094 8291 8462 9048 9589 10000 10151 10287 10783 10791 11094 11202 11279 11344 11786 12396 12651 12770 13052 13559 13693 13771 13946 14094 14202 14238 14250 14266 14272 14302 14306 14513 14718 14743 14766 14952 15223 15361 15408 15424 15453 15523 15663 16074 16186 17395 17888 18273 18797 20340 20363 20797 21389 21433 21435-21438 21696 22020 22071 22727 22769 22805 22807 22815 22837 22848-22850 22854 22859 22861 22863 22884 22887 22893 22907 22981 23076 23637 23782 23860 23945 24029 24108 24189 24562 24621 24925 25964 26057 26353 26381 26855 26886 27541 28137 28142 28688 28711 29054 29138 29161 30083 30325 30434 30438 30563 30919 31330 31398 31716 31744 31940 32019 32096 32165 32198 32297 32974 33008 33395 33935 33946 34875 35676 35756 35772 36119 36298 36341 36563 37181 37230-37231 37593 37721 37814 37932 38015 38174 38287 38291 38441 38980 39008 39162 39193 39202 39204 39263 39352 39515 39716 39877 40783 40882 41181 41320 41376 41516 41524 41565 41732 41924 42191 42416 42555 42586 42617 42670 42673 42684 42740 42903 42934 42944 42949 42956 42967 42984 43004 43127 43157 43285 43307 43332 43460 43843 44043 44074 44136 44258 44307 44310 44317 44352 44354 44371 44378 44451 44468 44651 44825 44833 44844 45430 45539 46008 46091 46436 46470 46768 46835 46856 47349 47539 47807 47824 48060 48203 482183.820087718822907e-19 3.820087718822907e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/AstBu/62.244?format=asciidefaultJ/other/AstBu/62.244/table2Parameters Z0, which characterizes the intensity of the {lambda}5200{AA} depression, and {Delta}X, which characterizes the degree of chemical anomaliesrecnoRecord number assigned by the VizieR team.
