cds-question@unistra.fropen-star-clustersgiant-starsline-intensitiesWe present detailed chemical compositions of 10 red giant star members of the Galactic (open) cluster NGC 752, derived from high-resolution (R~60000), high signal-to-noise (S/N>=140) spectra. We confirmed cluster memberships by measuring the stellar radial velocities, and by deriving model atmosphere parameters (Teff, logg, [Fe/H] and {xi}t) from equivalent widths of FeI, FeII, TiI, and TiII lines. The metallicity we obtained for NGC 752 ([Fe/H]=-0.02+/-0.05) is in good agreement with previous studies. We derived abundances of alpha (Mg, Si, Ca), light odd-Z (Na, Al), Fe-group (Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn), n-capture (Y, La, Nd, Eu), and p-capture (Li, C, N, O) species for each star. Furthermore, we also derived abundances of the LiCNO p-capture element group and carbon isotopic ratios, using synthetic spectrum analyses of the LiI 6707{AA} resonance doublet, the [OI] line at 6300{AA}, the CH G-band features near 4311 and 4325{AA}, the C_2_ bandheads at 5160 and 563{AA}, and ^12,13^CN red system lines in the 7995-8040{AA} region. By applying recent isochrones to NGC 752 photometry, and comparing the colour-magnitude diagram information to our Li abundances and 12C/13C ratios, we suggest that the 10 observed red giants can be separated into three first-ascent, six red-clump and one red horizontal branch star.2015MNRAS.446.3562Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/446/3562CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASP/106/281 : Photometry and radial velocities in NGC752 (Daniel+, 1994)J/A+A/339/423 : Velocities of red giants in NGC 752 (Mermilliod+ 1998)J/A+A/490/113 : X-ray sources in NGC 752 (Giardino+, 2008)J/A+A/485/303 : 1309 stars and 166 OCl radial velocities (Mermilliod+, 2008)J/MNRAS/419/1350 : Red giants abundances in 4 open clusters (Reddy+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/446/3562https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/446/3562http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/446/3562https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/446/3562https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/446/3562http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/446/3562GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/446/3562/stars (Observed NGC 752 red giants, observing logs and radial velocities (tables 2 & 3 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/446/3562/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/446/3562/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/446/3562/stars?GETtext/xml+votable180.050000true28.8025666737.837372220.0055555555555555566/2433 2436 2438https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/446/3562?format=asciiOpticaldefaultJ/MNRAS/446/3562/starsObserved NGC 752 red giants, observing logs and radial velocities (tables 2 & 3 of the paper)TexpExposure timestime.duration;obs.exposureintONameOther namemeta.idcharrecnoRecord number assigned by the VizieR team.
