VLT/NACO infrared adaptive optics images of small scale structures in OMC1
Résumé
Near-infrared observations of line emission from excited H2 and in the continuum are reported in the direction of the Orion molecular cloud OMC1, using the European Southern Observatory Very LargeTelescope UT4, equipped with the NAOS adaptive optics system and theCONICA infrared array camera. Spatial resolution has been achieved atclose to the diffraction limit of the telescope (0.08" - 0.12" ) and images show a wealthof morphological detail. Structure is not fractal but shows twopreferred scale sizes of 2.4" (1100 AU) and 1.2" (540 AU), where the larger scale may beassociated with star formation.
