The TESS-Keck Survey explained

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. The program has four main science themes:

  1. the bulk compositions of small planets
  2. dynamical temperatures and system architectures
  3. a larger, more refined sample for future atmospheric studies
  4. planets orbiting evolved stars
