cds-question@unistra.fratomic-physicsHD 143418 was discovered recently to be a double-lined spectroscopic binary with a primary designated as a CP star. Its light displays an orbital phase coupled variability with a peak-to-peak amplitude up to 0.04mag. The photometry available and new high dispersion spectra were investigated from a point of view of CP characteristics. A series of high resolution high S/N coude spectra was acquired from which 25 weak to strong unblended lines of Fe I and II, Ti II, Cr II, Zr II, and Ba II were selected to study spectral line variability. Two Zeeman spectra were obtained to search for a possible magnetic field of the star, and one echelle spectrum in a wide spectral region was analysed for abundance determination by means of synthetic spectra. The photometric observations were subjected to a PCA disentangling of the complex photometric behaviour.2009A&A...506..845Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/506/845CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/464/263 : UBV photometry of HD 143418 (Bozic+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/506/845https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/506/845http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/506/845https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/506/845https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/506/845http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/506/845GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/506/845/linesList of lines used in the spectrum of HD 143418 for abundance determinationrecnoRecord number assigned by the VizieR team.
