Single conjugate adaptive optics for the ELT instrument METIS
Stefan Hippler, Markus Feldt, Thomas Bertram +7
The ELT is a 39m large, ground-based optical and near- to mid-infrared telescope under construction in the Chilean Atacama desert. Operation is planned to start around the middle o…
STIM map: detection map for exoplanets imaging beyond asymptotic Gaussian residual speckle noise
Benoît Pairet, Faustine Cantalloube, Carlos A. Gomez Gonzalez +2
Direct imaging of exoplanets is a challenging task as it requires to reach a high contrast at very close separation to the star. Today, the main limitation in the high-contrast ima…
Exoplanet science with a space-based mid-infrared nulling interferometer
Sascha P. Quanz, Jens Kammerer, Denis Defrère +3
One of the long-term goals of exoplanet science is the (atmospheric) characterization of a large sample (>100) of terrestrial planets to assess their potential habitability and ove…
Characterizing the atmosphere of Proxima b with a space-based mid-infrared nulling interferometer
D. Defrère, A. Léger, O. Absil +9
Proxima b is our nearest potentially rocky exoplanet and represents a formidable opportunity for exoplanet science and possibly astrobiology. With an angular separation of only 35~…
Hi-5: a potential high-contrast thermal near-infrared imager for the VLTI
D. Defrère, M. Ireland, O. Absil +25
Hi-5 is a high-contrast (or high dynamic range) infrared imager project for the VLTI. Its main goal is to characterize young extra-solar planetary systems and exozodiacal dust arou…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes III. Technology opportunities and pathways
Frans Snik, Olivier Absil, Pierre Baudoz +30
The Optimal Optical CoronagraphWorkshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet instrumen…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes II. Common path wavefront sensing/control and Coherent Differential Imaging
Nemanja Jovanovic, Olivier Absil, Pierre Baudoz +28
The Optimal Optical Coronagraph (OOC) Workshop held at the Lorentz Center in September 2017 in Leiden, the Netherlands, gathered a diverse group of 25 researchers working on exopla…
Review of high-contrast imaging systems for current and future ground- and space-based telescopes I. Coronagraph design methods and optical performance metrics
G. Ruane, A. Riggs, J. Mazoyer +29
The Optimal Optical Coronagraph (OOC) Workshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet in…
Space-based infrared interferometry to study exoplanetary atmospheres
D. Defrère, A. Léger, O. Absil +30
The quest for other habitable worlds and the search for life among them are major goals of modern astronomy. One way to make progress towards these goals is to obtain high-quality…
The path towards high-contrast imaging with the VLTI: the Hi-5 project
D. Defrère, O. Absil, J. -P. Berger +26
The development of high-contrast capabilities has long been recognized as one of the top priorities for the VLTI. As of today, the VLTI routinely achieves contrasts of a few 10$^{-…
