Band-Limited Coronagraphs using a halftone-dot process: II. Advances and laboratory results for arbitrary telescope apertures
P. Martinez, C. Dorrer, M. Kasper
The band-limited coronagraph is a nearly ideal concept that theoretically enables perfect cancellation of all the light of an on-axis source. Over the past years, several prototype…
Higher-precision radial velocity measurements with the SOPHIE spectrograph using octagonal-section fibers
S. Perruchot, F. Bouchy, B. Chazelas +12
High-precision spectrographs play a key role in exoplanet searches using the radial velocity technique. But at the accuracy level of 1 m.s-1, required for super-Earth characterizat…
PIONIER: a 4-telescope visitor instrument at VLTI
Jean-Baptiste Le Bouquin, J. -P. Berger, B. Lazareff +43
PIONIER stands for Precision Integrated-Optics Near-infrared Imaging ExpeRiment. It combines four 1.8m Auxilliary Telescopes or four 8m Unit Telescopes of the Very Large Telescope…
Sparse aperture masking at the VLT I. Faint companion detection limits for the two debris disk stars HD 92945 and HD 141569
S. Lacour, P. Tuthill, P. Amico +4
Observational data on companion statistics around young stellar systems is needed to flesh out the formation pathways for extrasolar planets and brown dwarfs. Aperture masking is a…
Image reconstruction in optical interferometry: Benchmarking the regularization
Stéphanie Renard, Eric Thiébaut, Fabien Malbet
With the advent of infrared long-baseline interferometers with more than two telescopes, both the size and the completeness of interferometric data sets have significantly increase…
First fringes with an integrated-optics beam combiner at 10 um - A new step towards instrument miniaturization for mid-infrared interferometry
Lucas Labadie, Guillermo Martin, Norman C. Anheier +4
Observations at mas-resolution scales and high dynamic range hold a central place in achieving, for instance, the spectroscopic characterization of exo-Earths or the detailed mappi…
Optimized fringe sensors for the VLTI next generation instruments
N. Blind, O. Absil, J. -B. Lebouquin +2
Context. With the arrival of the next generation of ground-based imaging interferometers combining from 4 to possibly 6 telescopes simultaneously, there is also a strong need for a…
Simulation of planet detection with the SPHERE IFS
D. Mesa, R. Gratton, A. Berton +13
Aims. We present simulations of the perfomances of the future SPHERE IFS instrument designed for imaging extrasolar planets in the near infrared (Y, J, and H bands). Methods. We us…
Laboratory comparison of coronagraphic concepts under dynamical seeing and high-order adaptive optics correction
P. Martinez, E. Aller-Carpentier, M. Kasper +3
The exoplanetary science through direct imaging and spectroscopy will largely expand with the forthcoming development of new instruments at the VLT (SPHERE), Gemini (GPI), Subaru (…
A dual-band millimeter-wave kinetic inductance camera for the IRAM 30-meter telescope
A. Monfardini, A. Benoit, A. Bideaud +22
Context. The Neel IRAM KIDs Array (NIKA) is a fully-integrated measurement system based on kinetic inductance detectors (KIDs) currently being developed for millimeter wave astrono…
Planck early results: first assessment of the High Frequency Instrument in-flight performance
Planck HFI Core Team, P. A. R. Ade, N. Aghanim +163
The Planck High Frequency Instrument (HFI) is designed to measure the temperature and polarization anisotropies of the Cosmic Microwave Background and galactic foregrounds in six w…
Status of GDL - GNU Data Language
A. Coulais, M. Schellens, J. Gales +10
GNU Data Language (GDL) is an open-source interpreted language aimed at numerical data analysis and visualisation. It is a free implementation of the Interactive Data Language (IDL…
Planck Early Results. II. The thermal performance of Planck
Planck Collaboration, P. A. R. Ade, N. Aghanim +225
The performance of the Planck instruments in space is enabled by their low operating temperatures, 20K for LFI and 0.1K for HFI, achieved through a combination of passive radiative…
Planck Early Results: The Planck mission
Planck Collaboration, P. A. R. Ade, N. Aghanim +272
The European Space Agency's Planck satellite was launched on 14 May 2009, and has been surveying the sky stably and continuously since 13 August 2009. Its performance is well in li…
