Observational study of 290 exoplanet-host stars finds higher C, O, S, Fe, Ni abundances in giant-planet hosts than small-planet hosts, with C/O ratios, hot/warm differences, and mass correlations that vary by subpopulation.
New homogeneous abundances for 19 elements in 25 JWST planet-host stars show Tcond slopes independent of stellar and planetary properties after GCE correction, indicating mixed origins requiring careful interpretation.
