We report the detection of the orbital velocity of non-transiting hot Jupiter τ Boo b. By employing high-resolution ground-based spectroscopy around 2.3 μm during one half-night, we are able to detect carbon monoxide absorption lines produced in the planet atmosphere, which shift significantly in wavelength during the course of the observations due to the orbital motion of the planet. This detection of the planetary signal results in the determination of the orbital inclination as being i = 47…

High-dispersion ground-based spectroscopy of a transit of the extrasolar planet HD 209458b sees a significant wavelength shift in absorption lines from carbon monoxide in the planet’s atmosphere, which is concluded arises from a change in the radial component of the planet's orbital velocity.
