MARVEL : a 4-telescope array with a high resolution radial velocity spectrograph for measuring thousands of exoplanet masses, orbits and host star activity for the TESS, PLATO and ARIEL exoplanet space missions (MARVEL) KU Leuven
Since the first discovery of a planet outside of our Solar System in 1995, the exoplanet research has shifted from detecting to characterising worlds around other stars. The TESS (NASA, launched 2019) and PLATO mission (ESA, launch 2026) will find and constrain the size of thousands of exoplanets around bright stars all over the sky. Radial velocity measurements are needed to characterise the orbit and mass, and complete the picture of densities and composition of the exoplanet systems found. The ARIEL mission (ESA, launch 2028) will characterise exoplanet atmospheres with infrared ...
