Abundance differences, Δ [X/Fe] SUN − STARS, between the Sun and 10 stars hosting super-Earth-like planets (circles), 2 corresponding to the sample of “hot” analogs (top panels) and 8 belong to the sample of solar analogs analyzed in González Hernández et al. (2010). Error bars are the uncertainties of the element abundance measurements, corresponding to the line-by-line scatter. Diamonds show the average abundances in bins of ΔTC = 150 K. Error bars are the standard deviation from the mean abundance of the elements in each TC bin. Linear fits to the data points (solid line) and to the mean data points (dashed-dotted line) weighted with the error bars are also displayed.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
