Hydra spectra of 85 G-K dwarfs in the young cluster , M35 , near the Li 6708 Å line region are analyzed .
From velocities and Gaia astrometry , 78 are likely single-star members which , combined with previous work , produces 108 members with T _ { \mathrm { eff } } ranging from 6150 to 4000 K as defined by multicolor , broad-band photometry , E ( B - V ) = 0.20 and [ Fe/H ] = -0.15 , though there are indications the metallicity may be closer to solar .
A ( Li ) follows a well-delineated decline from 3.15 for the hottest stars to upper limits \leq 1.0 among the coolest dwarfs .
Contrary to earlier work , M35 includes single stars at systematically higher A ( Li ) than the mean cluster relation .
This subset exhibits higher V _ { ROT } than the more Li-depleted sample and , from photometric rotation periods , is dominated by stars classed as convective ( C ) ; all others are interface ( I ) stars .
The cool , high-Li rapid rotators are consistent with models that consider simultaneously rapid rotation and radius inflation ; rapid rotators hotter than the sun exhibit excess Li depletion , as predicted by the models .
The A ( Li ) distribution with color and rotation period , when compared to the Hyades/Praesepe and the Pleiades , is consistent with gyrochronological analysis placing M35 ’ s age between the older M34 and younger Pleiades .
However , the Pleiades display a more excessive range in A ( Li ) and rotation period than M35 on the low-Li , slow-rotation side of the distribution , with supposedly younger stars at a given T _ { \mathrm { eff } } in the Pleiades spinning slower , with A ( Li ) reduced by more than a factor of four compared to M35 .
