Segment-level thermal sensitivity analysis for exo-Earth coronagraphy with segmented space telescopes
Ananya Sahoo, Laurent Pueyo, Iva Laginja +5
The paper develops a thermal stability error budget for segmented space telescopes, linking temperature gradients on individual mirror segments to wavefront errors and defining seg…
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…
A parameter scan of dark zone maintenance for high-contrast imaging of exoplanets using theoretical and experimental implementations
Saikrishna Manojkumar, Christine L. Page, Leonid Pogorelyuk +14
Maintaining wavefront stability while directly imaging exoplanets over long exposure times is an ongoing problem in the field of high-contrast imaging. Robust and efficient high-or…
