We have developed a novel instrument called the Exoplanet Tracker (ET) that can measure precise radial velocities. ET is installed at the Kitt Peak 2.1m telescope and uses a Michelson interferometer in series with a medium resolution spectrograph, enabling high light-collection effeciency. A survey for exoplanet systems using ET has lead to the discovery of a hot-Jupiter planet around the star HD102195. We have also built a stable monolithic Michelson interferometer for ET, enabling higher stability and precision.
The development of the fixed-delay interferometer technology with the ET prototype has lead to the development of a large multi-object instrument capable of observing over 60 objects simultaneoulsy in the 3 degree field of view of the Sloan telescope. An upgraded version of this instrument will be used to conduct a large-scale survey for exoplanetary systems starting July 2008.
