Abstract:
JWST has ushered in an era of unprecedented ability to characterize
exoplanetary atmospheres. While there are over 5000 confirmed planets,
more than 4000 Transiting Exoplanet Survey Satellite (TESS) planet
candidates are still unconfirmed and many of the best planets for
atmospheric characterization may remain to be identified. We present a
sample of TESS planets and planet candidates that we identify as
"best-in-class" for transmission and emission spectroscopy with JWST.
These targets are sorted into bins across equilibrium temperature Teq
and planetary radius Rp and are ranked by a transmission and an
emission spectroscopy metric (TSM and ESM, respectively) within each
bin. We perform cuts for expected signal size and stellar brightness
to remove suboptimal targets for JWST. Of the 194 targets in the
resulting sample, 103 are unconfirmed TESS planet candidates, also
known as TESS Objects of Interest (TOIs). We perform vetting and
statistical validation analyses on these 103 targets to determine
which are likely planets and which are likely false positives,
incorporating ground-based follow-up from the TESS Follow-up
Observation Program to aid the vetting and validation process. We
statistically validate 18 TOIs, marginally validate 31 TOIs to varying
levels of confidence, deem 29 TOIs likely false positives, and leave
the dispositions for four TOIs as inconclusive. Twenty-one of the 103
TOIs were confirmed independently over the course of our analysis. We
intend for this work to serve as a community resource and motivate
formal confirmation and mass measurements of each validated planet. We
encourage more detailed analysis of individual targets by the
community.
