Left panel: distribution of the abundance slopes for the selected terrestrial planets. The planetary systems are further divided into two sub-groups: one with one or two planets (blue lines) and the other with more than two planets (orange lines). The distributions are normalized by the total number of PHSs in each category. Curved lines represent the KDE of each sub-group. The median slope for each sub-group is listed in the legend. The PHSs with larger numbers of planets are shifted toward more negative slopes. Right panel: same as in the left panel, but for the sub-Jovian (blue lines) and Jovian (orange lines) sub-groups. We considered the systems with RM < 5 R⊕ as sub-Jovian, while the one with RM ≥ 5 R⊕ -- astro-ph.SR

Connections Between Planetary Populations And The Chemical Characteristics Of Their Host Stars

Chemical anomalies in planet-hosting stars (PHSs) are studied in order to assess how the planetary nature and multiplicity affect the atmospheric chemical abundances of their host stars.
