Abstract

The novel Near Infrared Coronagraphic Imager (NICI) on the 8-m Gemini South telescope combines a number of techniques to attenuate starlight and suppress superspeckles for direct detection of exoplanets: 1) Lyot coronagraphic imaging, 2) dual channel imaging for Spectral Differential Imaging (SDI) and 3) operation in a fixed Cassegrain rotator mode for Angular Differential Imaging (ADI). The combination of these techniques allows unprecedented contrasts of dmag> 14 (median value) at 1" in H band. ...
