Olivier Guyon, Glenn Schneider, Ruslan Belikov, Domenick J., Tenerelli

TL;DR
EXCEDE is a NASA-selected technology demonstrator that aims to study exoplanetary systems and circumstellar environments with unprecedented sensitivity and resolution, paving the way for future exo-Earth characterization.
Contribution
It introduces a high-performance PIAA coronagraph integrated with a small telescope to achieve superior contrast and resolution for exoplanetary disk imaging.
Findings
Achieves contrast sensitivities ~1000x better than HST/JWST coronagraphs.
Provides high-resolution imaging of circumstellar disks at small inner working angles.
Demonstrates advanced wavefront control technology for future exoplanet imaging missions.
Abstract
We present an overview of the EXoplanetary Circumstellar Environments and Disk Explorer (EXCEDE), selected by NASA for technology development and maturation. EXCEDE will study the formation, evolution and architectures of exoplanetary systems, and characterize circumstellar environments into stellar habitable zones. EXCEDE provides contrast-limited scattered-light detection sensitivities ~ 1000x greater than HST or JWST coronagraphs at a much smaller effective inner working angle (IWA), thus enabling the exploration and characterization of exoplanetary circumstellar disks in currently inaccessible domains. EXCEDE will utilize a laboratory demonstrated high-performance Phase Induced Amplitude Apodized Coronagraph (PIAA-C) integrated with a 70 cm diameter unobscured aperture visible light telescope. The EXCEDE PIAA-C will deliver star-to-disk augmented image contrasts of < 10E-8 and a 1.2…
