Fig. 2


Chemical abundance ratios [X/Fe] versus [Fe/H] for the whole sample of “hot” analogs, containing 32 “single” stars (red open circles) and 29 stars hosting planets, with the most massive planet in an orbital period Porb < 65 days (green filled diamonds), 115 < Porb < 630 days (violet filled squares), 950 < Porb < 4050 days (orange filled triangles). Red solid lines provide linear fits to the data points of the 32 “single” stars, whereas blue dashed lines show the linear fits to the data points of “single” solar analogs in González Hernández et al. (2010).
