GRAVITY: beam stabilization and light injection subsystems
O. Pfuhl, M. Haug, F. Eisenhauer +9
We present design results of the 2nd generation VLTI instrument GRAVITY beam stabilization and light injection subsystems. Designed to deliver micro-arcsecond astrometry, GRAVITY r…
SOPHIE+: First results of an octagonal-section fiber for high-precision radial velocity measurements
F. Bouchy, R. F. Diaz, G. Hébrard +5
High-precision spectrographs play a key role in exoplanet searches and Doppler asteroseismology using the radial velocity technique. The 1 m/s level of precision requires very high…
An experimental testbed for NEAT to demonstrate micro-pixel accuracy
A. Crouzier, F. Malbet, O. Preis +10
NEAT is an astrometric mission proposed to ESA with the objectives of detecting Earth-like exoplanets in the habitable zone of nearby solar-type stars. In NEAT, one fundamental asp…
SOAP. A tool for the fast computation of photometry and radial velocity induced by stellar spots
I. Boisse, X. Bonfils, N. C. Santos
We define and put at the disposal of the community SOAP, Spot Oscillation And Planet, a software tool that simulates the effect of stellar spots and plages on radial velocimetry an…
NEAT: a space born astrometric mission for the detection and characterization of nearby habitable planetary systems
Fabien Malbet, Renaud Goullioud, Pierre-Olivier Lagage +4
The NEAT (Nearby Earth Astrometric Telescope) mission is a proposal submitted to ESA for its 2010 call for M-size mission within the Cosmic Vision 2015-2025 plan. The main scientif…
Review of small-angle coronagraphic techniques in the wake of ground-based second-generation adaptive optics systems
Dimitri Mawet, Laurent Pueyo, Peter Lawson +26
Small-angle coronagraphy is technically and scientifically appealing because it enables the use of smaller telescopes, allows covering wider wavelength ranges, and potentially incr…
Advances in the Development of Mid-Infrared Integrated Devices for Interferometric Arrays
L. Labadie, Guillermo Martin, Airan Rodenas +7
This article reports the advances on the development of mid-infrared integrated optics for stellar interferometry. The devices are fabricated by laser writing techniques on chalcog…
Observing planet-disk interaction in debris disks
Steve Ertel, Sebastian Wolf, Jens Rodmann
Context. Structures in debris disks induced by planetdisk interaction are promising to provide valuable constraints on the existence and properties of embedded planets. Aims. We in…
Imaging the heart of astrophysical objects with optical long-baseline interferometry
J. -P. Berger, F. Malbet, F. Baron +21
The number of publications of aperture-synthesis images based on optical long-baseline interferometry measurements has recently increased due to easier access to visible and infrar…
On the sensitivity of closure phases to faint companions in optical long baseline interferometry
Jean-Baptiste Le Bouquin, Olivier Absil
We explore the sensitivity and completeness of long baseline interferometric observations for detecting unknown, faint companions around bright unresolved stars. We derive a linear…
Circumstellar disks and planets. Science cases for next-generation optical/infrared long-baseline interferometers
Sebastian Wolf, Fabien Malbet, Richard Alexander +10
We present a review of the interplay between the evolution of circumstellar disks and the formation of planets, both from the perspective of theoretical models and dedicated observ…
FIRST, a fibered aperture masking instrument. I. First on-sky test results
E. Huby, G. Perrin, F. Marchis +12
In this paper we present the first on-sky results with the fibered aperture masking instrument FIRST. Its principle relies on the combination of spatial filtering and aperture mask…
Speckle Temporal Stability in eXtreme Adaptive Optics Coronagraphic Images
P. Martinez, C. Loose, E. Aller Carpentier +1
The major noise source limiting high-contrast imaging is due to the presence of quasi-static speckles. Speckle noise originates from wavefront errors caused by various independent…
Atmospheric characterization of cold exoplanets using a 1.5-m coronagraphic space telescope
A. -L. Maire, R. Galicher, A. Boccaletti +5
Context. High-contrast imaging is currently the only available technique for the study of the thermodynamical and compositional properties of exoplanets in long-period orbits. The…
SPICES: Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems
Anthony Boccaletti, Jean Schneider, Wes Traub +28
SPICES (Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems) is a five-year M-class mission proposed to ESA Cosmic Vision. Its purpose is to image and charact…
Kinetic inductance detectors for millimeter and submillimeter astronomy / Détecteurs à inductance cinétique pour l'astronomie millimétrique et sub-millimétrique
Nicolas Boudou, Alain Benoit, Olivier Bourrion +5
We present recent developments in Kinetic Inductance Detectors (KID) for large arrays of detectors. The main application is ground-based millimeter wave astronomy. We focus in part…
Active optics Shack-Hartmann sensor: using spot sizes to measure the seeing at the focal plane of a telescope
P. Martinez, J. Kolb, M. Sarazin +1
Real-time seeing estimation at the focus of a telescope is nowadays strongly emphasized as this knowledge virtually drives the dimensioning of adaptive optics systems and instrumen…
