Li abundances in solar-analog stars. II.

We carried out a comprehensive analysis of 118 solar analogs and reported that a close connection exists between the Li abundance (A_Li_) and the line-broadening width (v_r+m_) mainly contributed by rotational effect), which led us to conclude that stellar rotation may be the primary control of the surface Li content.

To examine our claim in more detail, we study whether the degree of stellar activity exhibits a similar correlation with the Li abundance, which is expected because of the widely believed close connection between rotation and activity.
