Scientific paper

STIS broad-band optical coronographic imaging will be used to search for circumstellar disks and indirect signatures of the presence of massive planets toward nearby Herbig Ae/Be and T Tauri stars. Each star will be observed at 2 orients, to facilitate separation of PSF artifacts from the circumstellar material. The program stars span 0.6-20 Myr and consist of a mixture of apparently single stars as well as binary systems. The observations consist of a suite of short CCD exposures which will be co-added on the ground to improve the S/N and enable detection of circumstellar material in the presence of stellar scattered light from the occulted star PSF. Cosmic ray identification and removal is handled by obtaining all images as CR-SPLIT=8, with the exception of our fainter targets which are CR-SPLIT=4. Questions: N/A
