Effect of Matter Accretion on Lithium Enhancement of Giants

A subset of low-mass giants (<2.2 M _⊙ ) exhibit anomalous lithium enhancement behavior, which is still an open topic. Given that more massive giants retain more surface lithium, increasing mass by accreting circumstellar matter could be a channel to enriching lithium. We evaluate this process in th...
