The positive correlation between planet detection rate and host star iron abundance lends
strong support to the core accretion theory of planet formation. However, iron is not the most …

We present evidence that stars with planets exhibit statistically significant silicon and nickel
enrichment over the general metal-rich population. We also present simulations that predict …

The mantra “know thy star, know thy planet” has proven to be very important for many
aspects of exoplanet science. Here I review how stellar abundances inform our …

The relationship between the compositions of giant planets and their host stars is of
fundamental interest in understanding planet formation. The solar system giant planets are …

Relating planet formation to atmospheric composition has been a long-standing goal of the
planetary science community. So far, most modeling studies have focused on predicting the …

We discuss dependence of extrasolar planetary systems on host stars' metallicity
(abundance of heavy elements) and mass (equivalently, spectral type), through theoretical …

Context. The chemical composition of planets is an important constraint for planet formation
and subsequent differentiation. While theoretical studies try to derive the compositions of …

The apparent dependence of detection frequency of extrasolar planets on the metallicity of
their host stars is investigated with Monte Carlo simulations using a deterministic core …

Correlations between stellar properties and the occurrence rate of exoplanets can be used
to inform the target selection of future planet-search efforts and provide valuable clues about …

We have recently carried out spectral synthesis modeling to determine T eff, log g, v sin i,
and [Fe/H] for 1040 FGK-type stars on the Keck, Lick, and Anglo-Australian Telescope planet …
