      abstract     = {Searches for Earth-like exoplanets using the periodic
                      Doppler shift of stellar absorption lines require 10 cm∕s
                      precision in the measurement of stellar radial velocity (RV)
                      over timescales of years. Current techniques have led to the
                      discovery of short-period exoplanets that induce RV wobbles
                      as small as ≈1 m∕s on their parent stars. It has been
                      suggested that order-of-magnitude improved RV precision may
                      be achievable using an astro-comb, a laser frequency comb
                      optimized for astrophysical spectrograph wavelength
                      calibration. Here we report the development of a broadband
                      visible-wavelength astro-comb and its operation with the
                      HARPS-N spectrograph at the Telescopio Nazionale Galileo in
                      the Canary Islands. This green astrocomb has >7000 narrow
                      (<1 MHz) spectral lines spaced by 16 GHz with relatively
                      uniform line power from 500 to 620 nm. The line frequencies
                      are locked to GPS, enabling us to realize HARPS-N wavelength
                      calibration with RV measurement precision and stability <10
