Laser-tracked Fabry-Perot etalons as wavelength calibrators for high-precision Doppler spectroscopy KU Leuven
Exoplanet space missions like TESS and PLATO require extensive follow-up through radial-velocity measurements from ground-based telescopes equipped with high-precision Doppler spectrographs. Radial velocity measurements are needed to characterise the orbit and mass, and complete the picture of densities and composition of the exoplanet systems found. These instruments' key performance issue is the availability of a long-term stable wavelength ...
