cds-question@unistra.fratomic-physicschemical-abundancesgiant-starsspectroscopyvisible-astronomyinfrared-astronomyWe derive a new abundance for vanadium in the bright, mildly metal-poor red giant Arcturus. This star has an excellent high-resolution spectral atlas and well-understood atmospheric parameters, and it displays a rich set of neutral vanadium lines that are available for abundance extraction. We employ a newly recorded set of laboratory FTS spectra to investigate any potential discrepancies in previously reported V I log(gf) values near 900nm. These new spectra support our earlier laboratory transition data and the calibration method utilized in that study. We then perform a synthetic spectrum analysis of weak V I features in Arcturus, deriving log{epsilon}(V)=3.54+/-0.01 ({sigma}=0.04) from 55 lines. There are no significant abundance trends with wavelength, line strength, or lower excitation energy.2018ApJS..234...25Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/234/25CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/pastel : The PASTEL catalogue (Soubiran+, 2016-)III/124 : Spectrophotometry of 60 stars (Kiehling, 1987)J/ApJS/111/445 : Spectra of normal stars in the K band (Wallace+ 1997)J/A+AS/129/237 : G and K dwarfs abundances (Feltzing+ 1998)J/A+A/439/129 : HERES II.
