The TESS-Keck Survey
Exoplanet search project
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]
- the bulk compositions of small planets
- dynamical temperatures and system architectures
- a larger, more refined sample for future atmospheric studies
- planets orbiting evolved stars
