ACS Coronographic Observations of Optically Thin Debris Disks
Abstract
The Advanced Camera for Surveys (ACS) offers a coronagraphic imaging mode with angular resolution of 0.026 arcsec per pixel. In combination with with the appropriate subtraction of reference star point spread functions (PSF) the coronagraph is capable of achieving contrast ratios of ~1000. We present some of the first ACS observations of the optically thin debris disk HD141569A and discuss new results from these observations.
