Paper Abstract

The TripleSpec - Exoplanet Discovery Instrument (TEDI) is a device to use interferometric spectroscopy for the radialvelocity detection of extrasolar planets at infrared wavelengths (0.9 - 2.4 μm). The instrument is a hybrid of an interferometer and a moderate resolution echelle spectrograph (TripleSpec, R=2,700,) at the Cassegrain focus of the Palomar 200" telescope. We describe our experimental diagnostic program using laboratory sources and standard stars in different optical configurations, along with performance analysis and results. We explain our instrumental upgrade development to achieve a long-term performance that can utilize our demonstrated, < 10 m/s, short-term velocity precision.
