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…

Coherent Differential Imaging of high-contrast extended sources with VLT/SPHERE

Axel Potier, Raphaël Galicher, Pierre Baudoz +6

High-contrast imaging relies on advanced coronagraphs and adaptive optics (AO) to attenuate the starlight. However, residual aberrations, especially non-common path aberrations bet…

JWST/MIRI observations of the young TWA 27 system: hydrocarbon disk chemistry, silicate clouds, evidence for a CPD

P. Patapis, M. Morales-Calderón, A. M. Arabhavi +39

The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST) enables the characterisation of young self-luminous gas giants at previously inaccessible wavelengths, r…

The planetary-mass-limit VLT/SINFONI library: Spectral extraction and atmospheric characterization via forward modeling

P. Palma-Bifani, M. Bonnefoy, G. Chauvin +9

We aim to deepen our understanding of the M-L transition on planetary-mass companions and isolated brown dwarfs, and search for evidence of possible differences between these two p…

MIRI-JWST mid-infrared direct imaging of the debris disk of HD106906

Daniel Rouan, Anthony Boccaletti, Clément Perrot +20

We report MIRI-JWST coronagraphic observations at 11.3 and 15.5 mic of the debris disk around the young star HD 106906. The observations were made to characterize the structure, te…

Extended Linearity in the High-Order Wavefront Sensor for the Roman Coronagraph

Iva Laginja, Pierre Baudoz, Johan Mazoyer +3

Context. The Coronagraphic Instrument (CGI) on the Roman Space Telescope aims for unprecedented contrast for direct imaging of exoplanets, serving as a critical tech demo for futur…
