Abstract:
The success of JWST has launched exoplanet science into a new era marked
by in-depth characterization of planetary atmospheres. It has also
underscored the importance of continuing ground-based observations for
understanding these systems. The High Resolution Echelle Spectrograph
(HIRES) at Keck has been one of the premier facilities for these
observations over the past 30 years paving the way for its successor the
Keck Planet Finder. In this talk, I will present preliminary results
from two surveys utilizing HIRES spectra: one to measure the masses of
planets themselves and another to determine the chemical abundances of
their host stars. The synergy of these measurements will be vital in our
effort to understand what these other worlds are comprised of.
