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…

Investigating three Sirius-like systems with SPHERE

R. Gratton, V. D'Orazi, T. A. Pacheco +61

Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…

Characterisation of a turbulent module for the MITHIC high-contrast imaging testbed

A. Vigan, M. Postnikova, A. Caillat +6

Future high-contrast imagers on ground-based extremely large telescopes will have to deal with the segmentation of the primary mirrors. Residual phase errors coming from the phase…

A medium-resolution spectrum of the exoplanet HIP 65426 b

Simon Petrus, Mickaël Bonnefoy, Gaël Chauvin +18

Medium-resolution integral-field spectrographs (IFS) coupled with adaptive-optics such as Keck/OSIRIS, VLT/MUSE, or SINFONI are appearing as a new avenue for enhancing the detectio…

A triple star in disarray -- Multi-epoch observations of T Tauri with VLT-SPHERE and LBT-LUCI

M. Kasper, K. K. R. Santhakumari, T. M. Herbst +24

T Tauri remains an enigmatic triple star for which neither the evolutionary state of the stars themselves, nor the geometry of the complex outflow system is completely understood.…

Direct imaging of sub-Jupiter mass exoplanets with James Webb Space Telescope coronagraphy

Aarynn L. Carter, Sasha Hinkley, Mariangela Bonavita +7

The James Webb Space Telescope (JWST), currently scheduled to launch in 2021, will dramatically advance our understanding of exoplanetary systems with its ability to directly image…
