Hertzsprung-Russell diagram of all the stars in our sample. Here we use the log(g) and T_eff derived in Tsantaki et al. (2023) for each star. The stars are coloured according to A(Li) and have different sizes to represent their different masses. The different symbols indicate how many strong correlations were found in a particular star: “•” indicates zero strong correlations, “★” indicates one strong correlation, and “+” indicates two or more strong correlations.
