Paper Abstract

We report narrow band adaptive optics near infrared imaging of the planetary nebula IC418. Our 25."6 x 25."6 images were recorded with the SHARP 11+ camera at the ESO 3.6m telescope, using the adaptive optics system ADONIS. The high spatial resolution was combined with the high spectral resolution provided by two Fabry-Perot etalons and a circular variable filter. Here we present images in the Br? and He I emission lines at 2.1655µm and 2.0581µm, respectively and discuss their astrophysical implications. Our results show that combining adaptive optics techniques with high spectral resolution opens a wide field of astrophysical studies.
