Abstract:
We present the stellar and planetary properties for 85 TESS Objects of
Interest (TOIs) hosting 108 planet candidates that compose the
TESS-Keck Survey (TKS) sample. We combine photometry, high-resolution
spectroscopy, and Gaia parallaxes to measure precise and accurate
stellar properties. We then use these parameters as inputs to a
light-curve processing pipeline to recover planetary signals and
homogeneously fit their transit properties. Among these transit fits,
we detect significant transit-timing variations among at least three
multiplanet systems (TOI-1136, TOI-1246, TOI-1339) and at least one
single-planet system (TOI-1279). We also reduce the uncertainties on
planet- to-star radius ratios Rp/R* across our sample, from a median
fractional uncertainty of 8.8% among the original TOI Catalog values
to 3.0% among our updated results. With this improvement, we are able
to recover the Radius Gap among small TKS planets and find that the
topology of the Radius Gap among our sample is broadly consistent with
that measured among Kepler planets. The stellar and planetary
properties presented here will facilitate follow-up investigations of
both individual TOIs and broader trends in planet properties, system
dynamics, and the evolution of planetary systems.
Description:
The TESS-Keck Survey (TKS) Collaboration has collected spectra for the
85 TOIs from Chontos+, 2022AJ....163..297C 2022AJ....163..297C at a spectral resolution of
R=50000 using the HIRES instrument at the W. M. Keck Observatory from
Summer 2019 to Fall 2022. We used iodine-free reconnaissance spectra,
with signal-to-noise ratio (S/N)∼40/pixel across 3600-9000Å, to
check for rapid stellar rotation and rule out spectroscopic false
positives.
