The lithium-rotation connection in the 125 Myr-old Pleiades cluster

Understand

The evolution of lithium abundance over a star's lifetime is indicative of transport processes operating in the stellar interior.

• We revisit the relationship between lithium content and rotation rate previously reported for cool dwarfs in the Pleiades cluster.
• We derive new LiI 670.8 nm equivalent width measurements from high-resolution spectra obtained for low-mass Pleiades members.
• We combine these new measurements with previously published ones, and use the Kepler/K2 rotational periods recently derived for Pleiades cool dwarfs to investigate the lithium-rotation connection in this 125 Myr-old cluster.
