Cascade adaptive optics with a second stage based on a Zernike wavefront sensor for exoplanet observations II. Validation in broadband light on the ESO/GHOST testbed
A. Rahim, M. N'Diaye, A. Vigan +10
Current high-contrast facilities on the ground use extreme adaptive optics (XAO) systems to achieve contrasts down to at 200\,mas for exoplanet observations. This perform…
The GPU-based High-order adaptive OpticS Testbench
Byron Engler, Markus Kasper, Serban Leveratto +12
The GPU-based High-order adaptive OpticS Testbench (GHOST) at the European Southern Observatory (ESO) is a new 2-stage extreme adaptive optics (XAO) testbench at ESO. The GHOST is…
Exoplanet imaging with ELTs: exploring a second-stage AO with a Zernike wavefront sensor on the ESO/GHOST testbed
Mamadou N'Diaye, Arthur Vigan, Byron Engler +6
We propose to explore a cascade extreme Adaptive optics (ExAO) approach with a second stage based on a Zernike wavefront sensor (ZWFS) for exoplanet imaging and spectroscopy. Most…
Lessons learned from the NEAR experiment and prospects for the upcoming mid-IR HCI instruments
Prashant Pathak, Markus Kasper, Olivier Absil +6
The mid-infrared (IR) regime is well suited to directly detect the thermal signatures of exoplanets in our solar neighborhood. The NEAR experiment: demonstration of high-contrast i…
PCS -- A Roadmap for Exoearth Imaging with the ELT
Markus Kasper, Nelly Cerpa Urra, Prashant Pathak +22
The Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT) will be dedicated to detecting and characterising nearby exoplanets with sizes from sub-Neptune…
Design, pointing control, and on-sky performance of the mid-infrared vortex coronagraph for the VLT/NEAR experiment
A. -L. Maire, E. Huby, O. Absil +16
Vortex coronagraphs have been shown to be a promising avenue for high-contrast imaging in the close-in environment of stars at thermal infrared (IR) wavelengths. They are included…
