The TESS-Keck Survey or TKS is an exoplanet search project that uses the Keck I and the Automated Planet Finder (APF) to conduct ground-based follow-up of planet candidates discovered by the Transiting Exoplanet Survey Satellite. [1] The TKS aims to measure the mass for about 100 exoplanets [2] and has been awarded some of the largest time allocations in the histories of Keck I and APF. [1] The program has four main science themes: [2]
