Chemical Abundances for 25 JWST Exoplanet Host Stars with KeckSpec.

Abstract (from CDS):

Using a data-driven machine learning tool we report Teff, $\mathrm{log}(g)$, $v\sin (i)$, and elemental abundances for 15 elements (C, N, O, Na, Mg, Al, Si, Ca, Ti, V, Cr, Mn, Fe, Ni, Y) for a sample of 25 exoplanet host stars targeted by JWST's first year of observations. The chemical diversity of these stars show that, while a number of their companion planets may have formed in a disk with chemistry similar to Solar, some JWST targets likely experienced different disk compositions. This sample is part of a larger forthcoming catalog that will report homogeneous abundances of ∼4500 FGK stars derived from Keck/HIRES optical spectra.
