title = "Precise infrared radial velocimetry with the Triplespec Exoplanet Discovery Instrument: Current performance and results",
abstract = "The TripleSpec Exoplanet Discovery Instrument (TEDI) is optimized to detect extrasolar planets orbiting midto- late M dwarfs using the Doppler technique at infrared wavelengths. TEDI is the combination of a Michelson interferometer and a moderate-resolution near-infrared spectrograph, TripleSpec, mounted on the Cassegrain focus of the Palomar 200-inch Hale Telescope. Here we present results from observations of a radial velocity standard star and a laboratory source over the past year. Our results indicate that focus effects within the interferometer, combined with non-common-path errors between the ThAr calibration source and starlight, limit our performance to several 100 m/s. An upgraded version of TEDI, TEDI 2.0, will eliminate this behavior by mixing ThAr with starlight in a scrambled fiber before a redesigned interferometer with minimal focal effects.",
