Based on these observations and data of 108 WTTSs taken from the literature, we derive lithium abundances for 127 WTTSs. Investigation of a possible relation between lithium and rotation in WTTSs shows that: (1) rapidly rotating WTTSs have comparatively lower lithium abundances than their slower rotating counterparts; (2) in the spectral-type range G0-K0, most of the WTTSs share the same Li content irrespective of their Teff; and (3) active late-type binaries do not obey the correlation between lithium abundances and rotation periods, since the tidally locked rotation of the late-type binary system leads naturally to slower lithium destruction rates.2010ApJ...723.1542Xhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/723/1542CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/479/827 : UBVR light curves of weak-line T Tauri stars (Grankin+, 2008)J/A+A/467/785 : SuperWASP/ROSAT periodic variable stars (Norton+, 2007)J/ApJ/667/308 : Weak-line T Tauri in Spitzer c2d Survey.
