cds-question@unistra.frspectroscopic-binary-starschemically-peculiar-starsline-intensitiesObservations of the mercury-manganese star phi Her with the Navy Prototype Optical Interferometer (NPOI) conclusively reveal the previously unseen companion in this single-lined binary system. The NPOI data were used to predict a spectral type of A8 V for the secondary star phi Her B. This prediction was subsequently confirmed by spectroscopic observations obtained at the Dominion Astrophysical Observatory. phi Her B is rotating at 50+/-3km/s, in contrast to the 8 km/s lines of phi Her A. Recognizing the lines from the secondary permits one to separate them from those of the primary. The abundance analysis of phi Her A shows an abundance pattern similar to those of other HgMn stars, with Al being very under-abundant and Sc, Cr, Mn, Zn, Ga, Sr, Y, Zr, Ba, Ce, and Hg being very overabundant.2007ApJ...655.1046Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/655/1046CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/367/597 : ups Her, phi Her + HR 7018 abundances (Adelman+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/655/1046https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/655/1046http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/655/1046https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/655/1046https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/655/1046http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/655/1046GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/655/1046/table2Astrometric solutions for {phi} HerrhoFitted binary separationmaspos.angDistance;meta.modelledfloatrecnoRecord number assigned by the VizieR team.
