Characterizing the performance of two C-RED ONE cameras for implementation in RISTRETTO and SAXO+ projects
Muskan Shinde, Jana Anouk Baron, Nicolas Blind +4
In the near-infrared wavelength regime, atmospheric turbulence fluctuates at a scale of a few milliseconds, and its precise control requires the use of extreme adaptive optics (XAO…
RISTRETTO: coronagraph and AO designs enabling High Dispersion Coronagraphy at 2 lambda/D
N. Blind, B. Chazelas, J. Kühn +13
RISTRETTO is the evolution of the original idea of coupling the VLT instruments SPHERE and ESPRESSO, aiming at High Dispersion Coronagraphy. RISTRETTO is a visitor instrument that…
KalAO the swift adaptive optics imager on 1.2m Euler Swiss telescope in La Silla, Chile
Janis Hagelberg, Nathanaël Restori, François Wildi +6
KalAO is a natural guide star adaptive optics (AO) imager to be installed on the second Nasmyth focus of the 1.2m Euler Swiss telescope in La Silla, Chile. The initial design of th…
RISTRETTO: a pathfinder instrument for exoplanet atmosphere characterization
Bruno Chazelas, Christophe Lovis, Nicolas Blind +8
We introduce the RISTRETTO instrument for ESO VLT, an evolution from the original idea of connecting the SPHERE high-contrast facility to the ESPRESSO spectrograph (Lovis et al 201…
An H-band Vector Vortex Coronagraph for the Subaru Coronagraphic Extreme-Adaptive Optics System
Jonas Kühn, Eugene Serabyn, Julien Lozi +11
The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This mult…
The Geneva Reduction and Analysis Pipeline for High-contrast Imaging of planetary Companions
J. Hagelberg, D. Ségransan, S. Udry +1
We present GRAPHIC, a new angular differential imaging (ADI) reduction pipeline where all geometric image operations are based on Fourier transforms. To achieve this goal the entir…
Artificial incoherent speckles enable precision astrometry and photometry in high-contrast imaging
Nemanja Jovanovic, Olivier Guyon, Frantz Martinache +3
State-of-the-art coronagraphs employed on extreme adaptive optics enabled instruments, are constantly improving the contrast detection limit for companions at ever closer separatio…
