Lick Planet Search
The Lick Observatory Planet Search (LPS) is the longest running exoplanet survey in the world. The Hamilton Spectrograph is used with either the 3-meter Shane Telescope or the 0.6-meter Coude Auxiliary Telescope (affectionately known as "The CAT") to measure the change in a star's radial velocity over time.
Some noteworthy discoveries credited to the Lick Observatory Planet Search include:
- confirmation of the first planet found to orbit a sun-like star (51 Peg b),
- the first multi-planet system (Ups And b, c, d), and
- the first five-planet system (55 Cnc b, c, d, e, f).
Additionally, major LPS contributions to the field include:
- the detection of planets around evolved stars,
- a catalog of over 2,600 stellar chromospheric activity measurements, and
- the planet-metallicity correlation.
