First high-contrast results on THD2 testbed after infrastructure upgrade
Iva Laginja, Pierre Baudoz, Rémi Soummer +17
We present the first scientific results delivered by the upgraded THD2 high-contrast imaging testbed. We report two advances enabled by its improved stability and broadband perform…
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…
Vector Apodizing Phase Plates for the ELT: From prototype to final optics for METIS and MICADO
J. A. van den Born, R. Landman, D. S. Doelman +12
The first generation of instruments for the upcoming Extremely Large Telescope (ELT) will allow for the direct imaging of exoplanets that were previously below the sensitivity or r…
SUPPPPRESS: Prototyping and testing liquid-crystal vector vortex coronagraphs with reduced polarization leakage
Rico Landman, David Doelman, Jeroen Rietjens +16
The vortex coronagraph is one of the most promising candidates for the Habitable Worlds Observatory (HWO) due to its excellent theoretical performance for an off-axis telescope. A…
The TOLIMAN mission: A low-cost space telescope for high precision narrow-angle astrometry
Peter Tuthill, Christopher Betters, Max Charles +29
The TOLIMAN project is engaged with the construction, launch and operation of a low-cost space telescope of unorthodox optical design. Its primary science goal targets an exhaustiv…
Chasing the storm: Investigating the application of high-contrast imaging techniques in producing precise exoplanet light curves
Ben J. Sutlieff, David S. Doelman, Jayne L. Birkby +10
Substellar companions such as exoplanets and brown dwarfs exhibit changes in brightness arising from top-of-atmosphere inhomogeneities, providing insights into their atmospheric st…
