The lithium abundances were derived using a detailed profile fitting of the LiI doublet at 6708{AA} in LTE. The planet-hosting and comparison stars were chosen to have significant overlap in their respective physical properties, including effective temperatures, luminosities, masses, metallicities, and ages. The combination of uniform data and homogeneous analysis with well-selected samples makes this study well suited to probe for possible differences in the lithium abundances found in planet-hosting stars. An overall comparison between the two samples reveals no obvious differences between stars with and without planets. A closer examination of the behavior of the Li abundances over a narrow range of effective temperature (5700K<=T_eff_<=5850K) indicates subtle differences between the two stellar samples; this temperature range is particularly sensitive to various physical processes that can deplete lithium.2010ApJ...724..154Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/724/154CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/720/1290 : Abundances of stars hosting planets (Ghezzi+, 2010)J/MNRAS/403/1368 : Li abundances for star-planet systems (Gonzalez+, 2010)J/A+A/515/A93 : Li abundances in solar-analog stars.
