GRAVITY: getting to the event horizon of Sgr A*
F. Eisenhauer, G. Perrin, W. Brandner +45
We present the second-generation VLTI instrument GRAVITY, which currently is in the preliminary design phase. GRAVITY is specifically designed to observe highly relativistic motion…
Wavefront error correction and Earth-like planet detection by Self-Coherent Camera in space
R. Galicher, P. Baudoz, G. Rousset
In the context of exoplanet detection, the performance of coronagraphs is limited by wavefront errors. To efficiently correct for these aberrations with a deformable mirror, it is…
Calibration and Pre-Compensation of Non-Common Path Aberrations for extreme Adaptive Optics
J. -F. Sauvage, T. Fusco, G. Rousset +1
Non-Common Path Aberrations (NCPA) are one of the main limitations for extreme Adaptive Optics (AO) system. NCPA prevent extreme AO systems to achieve their ultimate performance. T…
Post processing of differential images for direct extrasolar planet detection from the ground
J. -F. Sauvage, L. Mugnier, T. Fusco +1
The direct imaging from the ground of extrasolar planets has become today a major astronomical and biological focus. This kind of imaging requires simultaneously the use of a dedic…
ELTs Adaptive Optics for Multi-Objects 3D Spectroscopy : Key Parameters and Design Rules
B. Neichel, J-M. Conan, T. Fusco +4
In the last few years, new Adaptive Optics [AO] techniques have emerged to answer new astronomical challenges: Ground-Layer AO [GLAO] and Multi-Conjugate AO [MCAO] to access a wide…
Adaptive Optics Concept For Multi-Objects 3D Spectroscopy on ELTs
B. Neichel, T. Fusco, M. Puech +7
In this paper, we present a first comparison of different Adaptive Optics (AO) concepts to reach a given scientific specification for 3D spectroscopy on Extremely Large Telescope (…
