| Summary: | The Kepler and TESS missions have demonstrated that planets are ubiquitous. However, the success of these
missions heavily depends on ground-based radial velocity (RV) surveys, which combined with transit photometry
can yield bulk densities and orbital properties. While most Kepler host stars are too faint for detailed follow-up
observations, TESS is detecting planets orbiting nearby bright stars that are more amenable to RV characterization.
Here, we introduce the TESS-Keck Survey (TKS), an RV program using ∼100 nights on Keck/HIRES to study
exoplanets identified by TESS. The primary survey aims are investigating the link between stellar properties and
the compositions of small planets; studying how the diversity of system architectures depends on dynamical
configurations or planet multiplicity; identifying prime candidates for atmospheric studies with JWST; and
understanding the role of stellar evolution in shaping planetary systems. We present a fully automated target
selection algorithm, which yielded 103 planets in 86 systems for the final TKS sample. Most TKS hosts are
inactive, solar-like, main-sequence stars (4500 K Teff <6000 K) at a wide range of metallicities. The selected
TKS sample contains 71 small planets (Rp 4 R⊕), 11 systems with multiple transiting candidates, six sub-dayperiod planets and three planets that are in or near the habitable zone (Sinc 10 S⊕) of their host star. The target
selection described here will facilitate the comparison of measured planet masses, densities, and eccentricities to
predictions from planet population models. Our target selection software is publicly available and can be adapted
for any survey that requires a balance of multiple science interests within a given telescope allocation.
