Before the flood of discoveries resulting from NASA’s Kepler mission, the majority of extrasolar planets were found by analyzing precision radial velocity measurements of stars.
Periodic variations in a star’s radial velocity could be the result of reflex motion caused by an orbiting exoplanet. One of the longest running surveys of this type is the Lick-
Carnegie Exoplanet Survey (LCES) which has been running since 1994. On February 12, 2017 the LCES team including famed exoplanet hunters Paul Butler (Carnegie Institution for
Science), Steven Vogt (UCO/Lick Observatory) and Gregory Laughlin (Yale University), among others, submitted a paper for publication in the peer-reviewed Astrophysical Journal
with the results of their 20-year (and still counting) radial velocity survey. In addition, they have also made their data available to the public.
