Scientific paper

Since about an half-decade, adaptive optics (AO) on 8-10m class telescopes has been a key instrumentation for our understanding of Sgr A*. In this article, we frst remind the performances of the AO-fed NACO/VLT, with its infrared wavefront sensor, comparing them to other systems worldwide. We then present results obtained in imaging with NACO, on the dust clouds close to Sgr A*, more particularly on the closest one, Sgr A*-f, whose emission could result from a jet from Sgr A*. We fhally describe the spectroscopic observations of these dust clouds, performed very recently, using the low resolution prism mode of NACO.
