Segment-level thermal sensitivity analysis for exo-Earth coronagraphy with segmented space telescopes

Ananya Sahoo, Laurent Pueyo, Iva Laginja +5

Direct imaging and characterization of Earth-like planets require ultra-stable wavefronts to achieve a starlight suppression level of 100 parts per trillion (ppt) in the coronagrap…

Impact of segmented deformable mirrors on high-contrast testbeds for exoplanet imaging with future large space telescopes: contrast stability assessment on the HiCAT bench

Benjamin Buralli, Mamadou N'Diaye, Raphaël Pourcelot +13

We investigate the stability of a segmented deformable mirror (DM) on high-contrast testbeds and its impact on the images produced with coronagraphs. Segmented apertures are promis…
