Scientific paper

Near-infrared and high-precision have historically been disjoint adjectives to describe precision radial velocity searches. Recent advances have pushed precision in the near-infrared from 50 m/s with telluric wavelength calibration to 5 m/s with absorption gas cells. We have built a single gas, near-infrared absorption cell with greater line density and bandpass coverage than recently reported in the literature. We are currently carrying out a survey to detect exoplanets around red, low mass, and young stars. We discuss the current status of our survey, and new near-infrared instrumentation techniques that we are pursuing to complement optical radial velocity work.
