Adding colour to the Zernike wavefront sensor: Advantages of including multi-wavelength measurements for wavefront reconstruction
M. Darcis, S. Y. Haffert, V. Chambouleyron +3
To directly image Earth-like planets, contrast levels of 10^-8 - 10^-10 are required. The next generation of instruments will need wavefront control below the nanometer level to ac…
High-Contrast Coronagraphy
Matthew A. Kenworthy, Sebastiaan Y. Haffert
Imaging terrestrial exoplanets around nearby stars is a formidable technical challenge, requiring the development of coronagraphs to suppress the stellar halo of diffracted light a…
High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
BeyonCE -- Light Curve Modelling Beyond Circular Eclipsers I. Shallot Explorer
Dirk van Dam, Matthew Kenworthy
Context. Time-series photometry has given astronomers the tools to study time-dependent astrophysical phenomena, from stellar activity to fast radio bursts and exoplanet transits.…
Substellar and low-mass dwarf identification with near-infrared imaging space observatories
B. W. Holwerda, J. S. Bridge, R. Ryan +9
AIMS: We aim to evaluate the near-infrared colors of brown dwarfs as observed with four major infrared imaging space observatories: the Hubble Space Telescope (HST), the James Webb…
The Single-mode Complex Amplitude Refinement (SCAR) coronagraph: II. Lab verification, and toward the characterization of Proxima b
S. Y. Haffert, E. H. Por, C. U. Keller +4
We present the monochromatic lab verification of the newly developed SCAR coronagraph that combines a phase plate (PP) in the pupil with a microlens-fed single-mode fiber array in…
