Medium-resolution integral-field spectroscopy for high-contrast exoplanet imaging: Molecule maps of the Pictoris system with SINFONI
H. J. Hoeijmakers, H. Schwarz, I. A. G. Snellen +5
ADI and SDI are well-established high-contrast imaging techniques, but their application is challenging for companions at small angular separations. The aim of this paper is to inv…
Discovery of water at high spectral resolution in the atmosphere of 51 Peg b
J. L. Birkby, R. J. de Kok, M. Brogi +2
We report the detection of water absorption features in the dayside spectrum of the first-known hot Jupiter, 51 Peg b, confirming the star-planet system to be a double-lined spectr…
A framework to combine low- and high-resolution spectroscopy for the atmospheres of transiting exoplanets
M. Brogi, M. Line, J. Bean +2
Current observations of the atmospheres of close-in exoplanets are predominantly obtained with two techniques: low-resolution spectroscopy with space telescopes and high-resolution…
The slow spin of the young sub-stellar companion GQ Lupi b and its orbital configuration
Henriette Schwarz, Christian Ginski, Remco J. de Kok +3
The spin of a planet or brown dwarf is related to the accretion process, and therefore studying spin can help promote our understanding of the formation of such objects. We present…
Rotation and winds of exoplanet HD 189733 b measured with high-dispersion transmission spectroscopy
M. Brogi, R. J. de Kok, S. Albrecht +3
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 timescale…
Combining high-dispersion spectroscopy (HDS) with high contrast imaging (HCI): Probing rocky planets around our nearest neighbors
Ignas Snellen, Remco de Kok, Jayne Birkby +6
Aims: In this work, we discuss a way to combine High Dispersion Spectroscopy and High Contrast Imaging (HDS+HCI). For a planet located at a resolvable angular distance from its hos…
Evidence against a strong thermal inversion in HD 209458 b from high-dispersion spectroscopy
Henriette Schwarz, Matteo Brogi, Remco de Kok +2
Broadband secondary-eclipse measurements of hot Jupiters have indicated the existence of atmospheric thermal inversions, but their presence is difficult to determine from broadband…
A search for TiO in the optical high-resolution transmission spectrum of HD 209458b: Hindrance due to inaccuracies in the line database
H. J. Hoeijmakers, R. J. de Kok, I. A. G. Snellen +3
The spectral signature of an exoplanet can be separated from the spectrum of its host star using high-resolution spectroscopy. During such observations, the radial component of the…
The fast spin-rotation of a young extrasolar planet
Ignas Snellen, Bernhard Brandl, Remco de Kok +3
The spin-rotation of a planet arises from the accretion of angular momentum during its formation, but the details of this process are still unclear. In the solar system, the equato…
Carbon monoxide and water vapor in the atmosphere of the non-transiting exoplanet HD 179949 b
M. Brogi, R. J. de Kok, J. L. Birkby +2
(Abridged) In recent years, ground-based high-resolution spectroscopy has become a powerful tool for investigating exoplanet atmospheres. It allows the robust identification of mol…
On the colour of the dark side of the Moon
Peter Thejll, Chris Flynn, Hans Gleisner +5
Aims. 'Earthshine' is the dim light seen on the otherwise dark side of the Moon, particularly when it is close to new. 'Earthlight', or reflected sunlight from the Earth, is the so…
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…
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…
