PROVIDENCE: a ground station for space observation
P. -L. Mayeur, J. -F. Sauvage, T. Fusco +25
PROVIDENCE is an ONERA-led project to install a new-generation optical ground station at the Haute-Provence Observatory (OHP) in South of France. Built around a 2.5-meter aperture,…
The SPHERE infrared survey for exoplanets (SHINE) V. Full sample characterization
V. Squicciarini, S. Desidera, G. Chauvin +109
Unbiased surveys of large stellar samples are the prime means through which the prevalence of exoplanets can be derived, and crucial constraints to planet formation models can be s…
Optical gains measurement with a gain scheduling camera: On-sky demonstration with PAPYRUS and perspectives
A. Striffling, C. -T. Héritier, R. J. -L Fétick +4
Reaching the high angular resolution and contrast level desired for exoplanetary science requires us to equip large telescopes with extreme adaptive optics (XAO) systems to compens…
Estimating differential pistons for the Extremely Large Telescope using focal plane imaging and a residual network
P. Janin-Potiron, M. Gray, B. Neichel +6
As the Extremely Large Telescope (ELT) approaches operational status, optimising its imaging performance is critical. A differential piston, arising from either the adaptive optics…
