SAXO+, the second-stage adaptive optics for SPHERE: NCPA compensation and dark-hole loop with a pyramid wavefront sensor
Johan Mazoyer, Charles Goulas, Raphaël Galicher +21
The SAXO+ upgrade of the VLT/SPHERE adaptive optics system introduces a second-stage near-infrared pyramid wavefront sensor to improve high-contrast imaging, making accurate calibr…
Progress toward a demonstration of high contrast imaging at ultraviolet wavelengths
Kyle Van Gorkom, Ramya M. Anche, Christopher B. Mendillo +9
NASA's Habitable Worlds Observatory (HWO) aims to achieve starlight suppression to the level for the detection and spectral characterization of Earth-like exoplanets. Br…
Performance predictions and contrast limits for an ultraviolet high contrast imaging testbed
Kyle Van Gorkom, Ramya M. Anche, Christopher B. Mendillo +7
NASA's Habitable Worlds Observatory (HWO) concept and the 2020 Decadal Survey's recommendation to develop a large space telescope to "detect and characterize Earth-like extrasolar…
Heimdallr, Baldr and Solarstein: designing the next generation of VLTI instruments in the Asgard suite
Adam K. Taras, J. Gordon Robertson, Fatme Allouche +11
High angular resolution imaging is an increasingly important capability in contemporary astrophysics. Of particular relevance to emerging fields such as the characterisation of exo…
Ground-breaking Exoplanet Science with the ANDES spectrograph at the ELT
Enric Palle, Katia Biazzo, Emeline Bolmont +56
In the past decade the study of exoplanet atmospheres at high-spectral resolution, via transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular mapp…
Environmental transition: overview of actions to reduce the environmental footprint of astronomy
Lucie Leboulleux, Faustine Cantalloube, Marie-Alice Foujols +15
To keep current global warming below 1.5°C compared with the pre-industrial era, measures must be taken as quickly as possible in all spheres of society. Astronomy must also make i…
Upgrading the high contrast imaging facility SPHERE: science drivers and instrument choices
A. Boccaletti, G. Chauvin, F. Wildi +71
SPHERE+ is a proposed upgrade of the SPHERE instrument at the VLT, which is intended to boost the current performances of detection and characterization for exoplanets and disks. S…
Recovering saturated images for high dynamic Kernel-Phase analysis Application to the determination of dynamical masses for the system Gl 494AB
R. Laugier, F. Martinache, A. Ceau +3
Kernel-phase observables extracted from mid- to high-Strehl images are proving to be a powerful tool to probe within a few angular resolution elements of point sources. The attaina…
