cds-question@unistra.frpeculiar-variable-starschemically-peculiar-starsThe abundance pattern of six stars classified as suspected chemically peculiar in the General Catalogue of Ap and Am stars (<III/162>) by Renson has been derived to ascertain the real nature of these objects. Spectroscopic observations in the range {lambda}{lambda}4800-5600{AA} have been carried out at the stellar station of the INAF Catania Astrophysical Observatory. Among the studied stars, for only three of them we confirmed their peculiarity, HD 155102 being a silicon star, HD 159082 a mercury-manganese star and HD 162132 a moderate metallic A-type star. The other three objects have chemical abundances not so different from the standard values derived in the literature for A-type stars and, furthermore, they do not show light variability. Hence, we suggest that they could be ruled out from Renson's catalogue.2006MNRAS.368..247Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/368/247CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/162 : General Catalogue of Ap and Am stars (Renson+ 1991)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/368/247https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/368/247http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/368/247https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/368/247https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/368/247http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/368/247GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/368/247/table1 (Journal of observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/368/247/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/368/247/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/368/247/table1?GETtext/xml+votable180.050000true256.944496940.51605390.0055555555555555566/9491 9617 9683 29390 31928 32287https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/368/247?format=asciiOpticaldefaultJ/MNRAS/368/247/table1Journal of observationsHDHD numbermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
