cds-question@unistra.frap-starspeculiar-variable-starsstandard-starsmagnetic-fieldsSpectropolarimetric observations of 96 chemically peculiar (CP) main-sequence stars have been carried out at the 6-m telescope at the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS) with the aim of searching for the presence of stellar magnetic fields. The stars selected for investigation were CP stars known to have strong anomalies in the wavelength region of the continuum flux depression around {lambda} 5200{AA}. This selection was conducted with the aid of low-resolution spectral observations, made with the SAO RAS 1-m telescope, and of published differential photometric data. Magnetic fields have been successfully detected in 72 stars of which only three stars were previously known to have magnetic fields. For two stars, the longitudinal component of the magnetic field B_e_exceeds 5kG: HD178892 - 7.4kG, and HD258686 - 6.7kG. We failed to reliably detect the magnetic field in the other 24 CP stars. These stars are mostly fast rotators, a feature which hampers accurate measurements of B_e_. It is demonstrated in this paper that selecting candidate magnetic stars by considering their photometric indices Z or {Delta}alpha}, or alternatively, by inspecting low-resolution spectra around the {lambda}5200{AA} flux depression, considerably increases the detection rate.2006MNRAS.372.1804Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/372/1804CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/372/1804https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/372/1804http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/372/1804https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/372/1804https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/372/1804http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/372/1804GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/372/1804/sources (Studied sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/372/1804/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/372/1804/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/372/1804/sources?GETtext/xml+votable180.050000true1.9337917-2.54869440.0055555555555555566/1169 1359 1877 2395 2513 2677 2768 2817 2821 2953 3074 4668 6760 8291 9332 10142 12770 13199 13235 13771 13865 14057 14375-14376 14534 14565 14741 15631 16876 17397 17571 18315 18619 20437 21488 21807 22056 22077 22192-22193 22251 22262 22264 22279 22414 22831 22862 22867 22957 23010 23024 23030 23200 23410 23446 23556 23636 23641 23744 23937 23945 24005 24171 24298 24934 26592 27210 28035 28486 29081 29613 29984 30341 30378 30434 30500 30698 30703 31043 31078 31258 31260 31266 31710 31814 31871 32144 32193 32384 32580 33107 48582 49085https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/372/1804?format=asciidefaultJ/MNRAS/372/1804/sourcesStudied sourcesNNumber of measurements in table3.datmeta.numberintSimbadSimbad column added by the CDSmeta.ref.urlcharNameNamemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
