First Scattered-light Images of the Gas-rich Debris Disk around 49 Ceti

Choquet, Elodie Milli, Julien Wahhaj, Zahed

We present the first scattered-light images of the debris disk around 49 Ceti, a ~40 Myr A1 main-sequence star at 59 pc, famous for hosting two massive dust belts as well as large quantities of atomic and molecular gas. The outer disk is revealed in reprocessed archival Hubble Space Telescope NICMOS-F110W images, as well as new coronagraphic...

Lessons for WFIRST CGI from ground-based high-contrast systems

Bailey, Vanessa P. Bottom, Michael Cady, Eric

The Coronagraph Instrument (CGI) for NASA's Wide Field Infrared Survey Telescope (WFIRST) will constitute a dramatic step forward for high-contrast imaging, integral field spectroscopy, and polarimetry of exoplanets and circumstellar disks, aiming to improve upon the sensitivity of current ground-based direct imaging facilities by 2-3 orders of...
