The optical high-resolution spectral archive of the HERMES spectrograph mounted on the 1.2m Mercator telescope
Hans Van Winckel, Saskia Prins, Gert Raskin +13
Context. The HERMES spectrograph is a high-resolution, fibre-fed optical spectrograph of the 1.2m Mercator telescope operated from the Roque de los Muchachos observatory in Spain.…
Advancing European High-Contrast Imaging R&D Towards the Habitable Worlds Observatory
Iva Laginja, Óscar Carrión-González, Romain Laugier +31
The Habitable Worlds Observatory (HWO) will enable a transformative leap in the direct imaging and characterization of Earth-like exoplanets. For this, NASA is focusing on early in…
Reference star differential imaging of close-in companions and circumstellar disks with the NIRC2 vortex coronagraph at W.M. Keck Observatory
Garreth Ruane, Henry Ngo, Dimitri Mawet +11
Reference star differential imaging (RDI) is a powerful strategy for high contrast imaging. Using example observations taken with the vortex coronagraph mode of Keck/NIRC2 in $L^\p…
Hi-5: a potential high-contrast thermal near-infrared imager for the VLTI
D. Defrère, M. Ireland, O. Absil +25
Hi-5 is a high-contrast (or high dynamic range) infrared imager project for the VLTI. Its main goal is to characterize young extra-solar planetary systems and exozodiacal dust arou…
The path towards high-contrast imaging with the VLTI: the Hi-5 project
D. Defrère, O. Absil, J. -P. Berger +26
The development of high-contrast capabilities has long been recognized as one of the top priorities for the VLTI. As of today, the VLTI routinely achieves contrasts of a few 10$^{-…
