Scientific paper

We present astrometry and photometry on a sample of stars at distances between 8 and 16 parsecs imaged with the Johns Hopkins’ Adaptive Optics Coronagraph mounted on the Palomar 60-inch telescope from September, 1998 to November, 2000. These data (taken in the Gunn r, i, and z filters) extend the 8 parsec sample from Oppenheimer et al. (2001) originally used to identify the brown dwarf GL 229B. Coronagraphic imaging allows the occlusion of a bright central star, thus permitting the direct imaging of spatially nearby objects otherwise not visible. This technique is particularly useful in the search for low mass/luminosity companions close to bright stars. This work was supported by a grant from NASA's Jet Propulsion Lab number 1303801.
