Towards Autodifferentiable Point Spread Function Modelling for the VLT/ERIS Vortex Coronagraph
P. Van de Walle Suarez, G. Orban De Xivry, O. Absil +3
High-contrast imaging of exoplanets is limited by the presence of quasi-static speckles and existing post-processing methods remain above the theoretical noise limit. We investigat…
Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
The paper reports the direct imaging discovery of a third giant exoplanet, β Pictoris d, using VLT/ERIS and archival JWST/NIRCam and VLT/SPHERE data, and characterizes its orbit, t…
Multi-epoch scattered-light analysis of HD 135344B: new evidence for a spiral-driving protoplanet
J. Latour, V. Christiaens, O. Absil +17
The HD 135344B (SAO 206462) disk exhibits strong signposts of planet formation. ALMA images in the sub-mm revealed a gap-crossing dust filament whose position coincides with a twis…
The VLT/ERIS grating vector Apodizing Phase Plate coronagraph
M. A. Kenworthy, F. A. Dannert, J. Hayoz +29
We describe the design, laboratory manufacture, and on-sky testing of the grating vector apodizing phase plate (gvAPP) coronagraph for the Enhanced Resolution Imager and Spectrogra…
Constraining nearby substellar companion architectures using High Contrast Imaging, Radial Velocity and Astrometry data
L. F. Sartori, M. J. Bonse, Y. Li +3
Nearby stars offer prime opportunities for exoplanet discovery and characterization through various detection methods. By combining HCI, RV, and astrometry, it is possible to bette…
Consequences of Non-Gaussian Instrumental Noise in Perturbed Nulling Interferometers
Felix A. Dannert, Philipp A. Huber, Thomas Birbacher +6
With the astrophysics community working towards the first observations and characterizations of Earth-like exoplanets, interest in space-based nulling interferometry has been renew…
