[67.15] NICMOS Coronagraphic Observations of Circumstellar Environments - Preliminary Results

G. Schneider, R. Thompson (U. of Arizona), E. Becklin (U. of California), B. Smith (U. of Hawaii), R. Terrile (JPL)

The NICMOS camera 2 coronagraph provides a unique instrumental resource for exploring circumstellar environments. The NICMOS Environments of Nearby Stars (EONS) programs recently commenced following the completion of the commissioning of the coronagraph in February, 1998. Under those programs we are conducting systematic surveys of nearby, and young stars searching for companion brown dwarfs and giant planets, and protoplanetary disks around main-sequence stars. We present the status of these and related programs along with a summary of preliminary results.
