Near-infrared adaptive optics imaging of dust shells around five late-type stars with COME-ON+
Abstract
Near-infrared images of circumstellar dust shells around five late type stars have been obtained with the ESO - COME-ON+ adaptive optics system in 1994 September. Full angular resolution of the 3.60 m ESO - La Silla telescope was achieved at 1.25, 1.65 and 2.2 microns (respectively 0.09, 0.12 and 0.15 \arcsec of angular resolution). A dynamic range of 1000:1 is obtained in the images. Based on observations collected at the European Southern Observatory, La Silla (Chile)
