High-contrast imaging of debris disk systems permits us to assess the composition and size distribution of circumstellar dust, to probe recent dynamical histories, and to directly detect and characterize embedded exoplanets. Observations of these sys

The Near Infrared Camera for the James Webb Space Telescope (JWST) is delivering the imagery that astronomers have hoped for ever since JWST was proposed back in the 1990s. In the Commissioning Period that extended from right after launch to early 20

In a cold and stable space environment, the James Webb Space Telescope (JWST or "Webb") reaches unprecedented sensitivities at wavelengths beyond 2 microns, serving most fields of astrophysics. It also extends the parameter space of high-contrast ima

Techniques and Instrumentation for Detection of Exoplanets X.
During days-long exposure of the Roman Space Telescope (RST) Coronographic Instrument (CGI), the starlight wavefront will drift due to thermal instabilities of the optical tube assembly (OTA) and deformable mirror (DM) actuators. While low-order spat
