Identifying new opportunities for exoplanet characterisation at high spectral resolution
Remco J. de Kok, Jayne Birkby, Matteo Brogi +4
[Abridged] Recently, there have been a series of detections of molecules in the atmospheres of extrasolar planets using high spectral resolution (R~100,000) observations, mostly us…
Searching for transits in the WTS with difference imaging light curves
Jesus Zendejas, Johannes Koppenhoefer, Roberto P. Saglia +13
The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses ape…
Detection of water absorption in the day side atmosphere of HD 189733 b using ground-based high-resolution spectroscopy at 3.2 microns
J. L. Birkby, R. J. de Kok, M. Brogi +4
We report a 4.8 sigma detection of water absorption features in the day side spectrum of the hot Jupiter HD 189733 b. We used high-resolution (R~100,000) spectra taken at 3.2 micro…
Detection of carbon monoxide in the high-resolution day-side spectrum of the exoplanet HD 189733b
Remco J. de Kok, Matteo Brogi, Ignas A. G. Snellen +3
[Abridged] After many attempts over more than a decade, high-resolution spectroscopy has recently delivered its first detections of molecular absorption in exoplanet atmospheres, b…
A sensitivity analysis of the WFCAM Transit Survey for short-period giant planets around M dwarfs
Gábor Kovács, S. Hodgkin, B. Sipőcz +11
The WFCAM Transit Survey (WTS) is a near-infrared transit survey running on the United Kingdom Infrared Telescope (UKIRT), designed to discover planets around M dwarfs. The WTS act…
A highly unequal-mass eclipsing M-dwarf binary in the WFCAM Transit Survey
S. V. Nefs, J. L. Birkby, I. A. G. Snellen +6
In this paper we present the discovery of a highly unequal-mass eclipsing M-dwarf binary, providing a unique constraint on binary star formation theory and on evolutionary models f…
Detection of molecular absorption in the dayside of exoplanet 51 Pegasi b?
M. Brogi, I. A. G. Snellen, R. J. de Kok +3
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 3x5 hours at 2.3 μm at a spect…
Finding extraterrestrial life using ground-based high-resolution spectroscopy
Ignas Snellen, Remco de Kok, Rudolf Le Poole +2
Exoplanet observations promise one day to unveil the presence of extraterrestrial life. Atmospheric compounds in strong chemical disequilibrium would point to large-scale biologica…
