Description
Spectrographs for radial velocities evolved from the specifications required for Galactic dynamics studies to those set by exoplanet mass characterization. As time went by, the search for lower-mass planets on longer periods pushed for higher measurement precision and improved instrument stability. But the detection of a transiting planet in 2000 and an exo-atmosphere in 2010 reshuffled scientific priorities. Today, atmosphere characterization is done mostly on spectrographs designed for precise RVs, and yet is having a field day at it.
