Focal Plane Wavefront Sensing on SUBARU/SCExAO

Sebastien Vievard, Steven P. Bos, Frederic Cassaing +20

Focal plane wavefront sensing is an elegant solution for wavefront sensing since near-focal images of any source taken by a detector show distortions in the presence of aberrations…

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…

Direct characterization of young giant exoplanets at high spectral resolution by coupling SPHERE and CRIRES+

G. P. P. L. Otten, A. Vigan, E. Muslimov +19

Studies of atmospheres of directly imaged exoplanets with high-resolution spectrographs have shown that their characterization is predominantly limited by noise on the stellar halo…

Increasing the raw contrast of VLT/SPHERE with the dark hole technique. I. Simulations and validation on the internal source

Axel Potier, Raphaël Galicher, Pierre Baudoz +7

Context. Since 1995 and the first discovery of an exoplanet orbiting a main-sequence star, 4000 exoplanets have been discovered using several techniques. However, only a few of the…

Angular differential kernel phases

Romain Laugier, Frantz Martinache, Nick Cvetojevic +7

To reach its optimal performance, Fizeau interferometry requires that we work to resolve instrumental biases through calibration. One common technique used in high contrast imaging…

Kernel-phase analysis: aperture modeling prescriptions that minimize calibration errors

Frantz Martinache, Alban Ceau, Romain Laugier +5

Kernel-phase is a data analysis method based on a generalization of the notion of closure-phase invented in the context of interferometry, but that applies to well corrected diffra…
