Paper Abstract

With its high Strehl ratio near- and mid-infrared imaging capabilities, wide field of view, and multiple spectroscopic options, the James Webb Space Telescope (JWST) will provide crucial information on the circumstellar environments of stars thought to harbor debris disks, brown dwarfs or extrasolar giant planets. However, the successful study of such faint targets around nearby, bright stars requires the effective removal of the target star's contribution from the image. In this work, we use simple models of the temporal behavior JWST's wavefront error of JWST over time to examine whether frequent measurements of that changing wavefront can be used to provide an effective point spread function subtraction for high-contrast imaging studies without use of coronagraphic techniques.
