Astrometry with the Wide-Field Infrared Space Telescope

Casertano, Stefano; Lu, Jessica R.; Anderson, Jay +15 more

The Wide-Field Infrared Space Telescope (WFIRST) will be capable of delivering precise astrometry for faint sources over the enormous field of view of its main camera, the Wide-Field Imager (WFI). This unprecedented combination will be transformative for the many scientific questions that require precise positions, distances, and velocities of sta…

ExoEarth yield landscape for future direct imaging space telescopes

Stark, Christopher C.; Mazoyer, Johan; Pueyo, Laurent +19 more

The expected yield of potentially Earth-like planets is a useful metric for designing future exoplanet-imaging missions. Recent yield studies of direct-imaging missions have focused primarily on yield methods and trade studies using "toy" models of missions. Here, we increase the fidelity of these calculations substantially, adopting more realisti…

Colorado Ultraviolet Transit Experiment data simulator

France, Kevin; Rüdisser, Hannah T.; Koskinen, Tommi +5 more

The Colorado Ultraviolet Transit Experiment (CUTE) is a 6U NASA CubeSat carrying on board a low-resolution (R ∼ 2000 to 3000), near-UV (2500 to 3300 Å) spectrograph. It has a rectangular primary Cassegrain telescope to maximize the collecting area. CUTE, which is planned for launch in spring 2020, is designed to monitor transiting extra-solar plan…
