Figure 1: Abundance ratios [X/H] plotted vs. the elemental condensation temperatures for the planet host HD 20367 and HD 39091 ( left panels), and for the comparison sample stars HD 23484 and HD 69830 ( right panels). The solid lines represent the linear least-squares fits to the data. The slopes values and the typical error bars associated with the [X/H] ratios are indicated at the bottom and the top of each plot, respectively. | |

Figure 2: Slopes derived from [X/H] vs. for all the planet host ( filled symbols) and comparison sample ( open symbols) stars. The solid lines represent the average slope of the two samples, and the average slope one standard deviation. The dotted and dashed lines indicate the average slope of stars with and without planets, respectively. | |

Figure 3: [X/H] vs. slopes plotted vs. [Fe/H] for all the planet host ( filled symbols) and comparison sample ( open symbols) stars. The solid lines represent the linear least-squares fit 2 for all the targets, while the dotted and dashed lines indicate the linear least-squares fits 2 for stars with and without planets, respectively. The slopes of each linear fit are shown at the bottom. | |

Figure 4: Abundance ratios [X/H] plotted vs. the elemental condensation temperatures for the planet host stars HD 169830 and HD 114783, having slopes more than 2 below the slopes vs. [Fe/H] fit. The solid lines represent the linear least-squares fits to the data. The slopes values and the typical error bars associated with the [X/H] ratios are indicated at the bottom and the top of each plot, respectively. | |
