Exploiting symmetries and progressive refinement for apodized pupil Lyot coronagraph design
Emiel H. Por, Rémi Soummer, James Noss +1
Modern coronagraph design relies on advanced, large-scale optimization processes that require an ever increasing amount of computational resources. In this paper, we restrict ourse…
Estimating low-order aberrations through a Lyot coronagraph with a Zernike wavefront sensor for exoplanet imaging
Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady +13
Imaging exo-Earths is an exciting but challenging task because of the 10^-10 contrast ratio between these planets and their host star at separations narrower than 100 mas. Large se…
High contrast imaging for the enhanced resolution imager and spectrometer (ERIS)
Matthew A. Kenworthy, Frans Snik, Christoph U. Keller +9
ERIS is a diffraction limited thermal infrared imager and spectrograph for the Very Large Telescope UT4. One of the science cases for ERIS is the detection and characterization of…
Detection of polarization neutral points in observations of the combined corona and sky during the 21 August 2017 total solar eclipse
Frans Snik, Steven P. Bos, Stefanie A. Brackenhoff +7
We report the results of polarimetric observations of the total solar eclipse of 21 August 2017 from Rexburg, Idaho (USA). We use three synchronized DSLR cameras with polarization…
SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
The wind-driven halo in high-contrast images I: analysis from the focal plane images of SPHERE
Faustine Cantalloube, Ollie Farley, Julien Milli +9
Context. The wind driven halo is a feature observed within the images delivered by the latest generation of ground-based instruments equipped with an extreme adaptive optics system…
