The JWST Debris Disk Spatially Resolved Imaging GTO Programs

The James Webb Space Telescope (JWST) Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) science groups are devoting over 80 hours of their Guaranteed Time Observations (GTO) to spatially resolve the circumstellar disks of some of the most prominent nearby systems. Both instruments have coronagraphic imaging capabilities, enabling complementary scientific programs to be carried out at different wavelength regimes. In our presentation we will introduce the coronagraphic capabilities of the Observatory and detail the observing programs we will execute in Cycles 1 and 2. The primary goal of the MIRI Archetypical Debris Disks GTO program is to spatially resolve the Asteroid belt analog components of the three nearest and highest fractional infrared luminosity systems: Fomalhaut, Vega, and epsilon Eridani. The MIRI coronagraph is the only current instrument capable of achieving this goal. Complementary to the MIRI observations, the NIRCam Moonshots program will image these three systems with the NIRCam coronagraphs to search for exoplanets via direct imaging. Our NIRcam scattered light program will additionally observe five nearby debris disks that have been previously imaged with the Hubble Space Telescope at optical wavelengths with ACS and/or STIS. The systems are: HD 107146, HD 181327, HD 10647, HD 61005, and HD 32297. By imaging the systems at multiple infrared wavelengths accross the 3 micron water line, we will study the chemical composition of the disks and its spatial distribution. Additionally, dynamical studies of dust transport via radiative forces and gravitational perturbation via planets will also be possible. Our presentation will also explain the observing techniques and strategies we employ in our GTO programs and also introduce JWST coronagraphic imaging simulators we developed to aid preparations of GO corongaraphic programs for Cycle 1.
