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…

The return of the mummy: Evidence for starlight reflected from the massive hot Jupiter τ Boo b?
Very recently, we were able to measure CO absorption features in the atmosphere of the non-transiting planet τ Boo b for the very first time. This allowed us to unravel a long-term mystery in planet
NEAR-IR DIRECT DETECTION OF WATER VAPOR IN TAU BOÖTIS b
We use high dynamic range, high-resolution L-band spectroscopy to measure the radial velocity (RV) variations of the hot Jupiter in the τ Boötis planetary system. The detection of an exoplanet by the
Detection of Water Vapor in the Thermal Spectrum of the Non-Transiting Hot Jupiter upsilon Andromedae b
The Upsilon Andromedae system was the first multi-planet system discovered orbiting a main-sequence star. We describe the detection of water vapor in the atmosphere of the innermost non-transiting
ROTATION AND WINDS OF EXOPLANET HD 189733 b MEASURED WITH HIGH-DISPERSION TRANSMISSION SPECTROSCOPY
Giant exoplanets orbiting very close to their parent star (hot Jupiters) are subject to tidal forces expected to synchronize their rotational and orbital periods on short timescales (tidal locking).
Constraining the orbit of the planet-hosting binary τ Boötis
Context. The formation of planets in compact or highly eccentric binaries and the migration of hot Jupiters are two outstanding problems in planet formation. Detailed characterisation of known
Discovery of water at high spectral resolution in the atmosphere of 51 Peg b
We report the detection of water absorption features in the day side spectrum of the first-known hot Jupiter, 51 Peg b, confirming the star–planet system to be a double-lined spectroscopic binary. We
Future Direct Spectroscopic Detection of Hot Jupiters with IGRINS
With about 700 confirmed extrasolar planets, it is time to move beyond discovery and towards characterization. Perhaps the most basic parameter of an extrasolar planet is its mass; however, this is
DETECTION OF MOLECULAR ABSORPTION IN THE DAYSIDE OF EXOPLANET 51 PEGASI b?
In this paper, we present ground-based high-resolution spectroscopy of 51 Pegasi using CRIRES at the Very Large Telescope. The system was observed for 3 × 5 hr at 2.3 μm at a spectral resolution of R

Ground-based high-dispersion spectroscopy could reveal molecular oxygen as a biomarker gas in the atmospheres of twin-Earths transiting red dwarf stars within the next 25 years. The required
EVIDENCE FOR THE DIRECT DETECTION OF THE THERMAL SPECTRUM OF THE NON-TRANSITING HOT GAS GIANT HD 88133 b
We target the thermal emission spectrum of the non-transiting gas giant HD 88133 b with high-resolution near-infrared spectroscopy, by treating the planet and its host star as a spectroscopic binary.

The orbital motion, absolute mass and high-altitude winds of exoplanet HD 209458b
TLDR
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.
