Lithium in Wide Binaries: Effective Temperature Governs Depletion while Rotation Plays a Minor Role

Cheng-Cheng Xie, Hai-Jun Tian, Jian-Rong Shi +1

Using a sample of 116 wide binary systems as coeval and chemically homogeneous stellar pairs, we investigate the factors governing lithium depletion in main-sequence stars. We reco…
