Abstract:
With JWST's successful deployment and unexpectedly high fuel reserves,
measuring the masses of sub-Neptunes transiting bright, nearby stars
will soon become the bottleneck for characterizing the atmospheres of
small exoplanets via transmission spectroscopy. Using a carefully
curated target list and observations from more than 2yr of APF-Levy
and Keck-HIRES Doppler monitoring, the TESS-Keck Survey is working
toward alleviating this pressure. Here we present mass measurements
for 11 transiting planets in eight systems that are particularly
suited to atmospheric follow-up with JWST. We also report the
discovery and confirmation of a temperate super-Jovian-mass planet on
a moderately eccentric orbit. The sample of eight host stars, which
includes one subgiant, spans early-K to late-F spectral types
(Teff=5200-6200K). We homogeneously derive planet parameters using a
joint photometry and radial velocity modeling framework, discuss the
planets possible bulk compositions, and comment on their prospects for
atmospheric characterization.
Description:
Each system was observed in at least two sectors, with HD 135694 being
observed in 14.
