VizieR Online Data Catalog: Lithium content of ω Cen (Monaco+, 2010)
Abstract
We obtained moderate resolution (R=17000) spectra for 91 main-sequence/early sub-giant branch (MS/SGB) omega Cen stars using the FLAMES-GIRAFFE/VLT spectrograph. Lithium abundances were derived by matching the equivalent width of the LiI resonance doublet at 6708Å to the prediction of synthetic spectra computed with different Li abundances. Synthetic spectra were computed using the SYNTHE code along with ATLAS-9 model atmospheres. The stars effective temperatures are derived by fitting the wings of the Hα line with synthetic profiles. Observations were taken on three nights of 27-29 April 2007 using the FLAMES/VLT spectrograph at ESO Paranal.
