Abstract: (arXiv)
We present adaptive optics high angular resolution (\sim0\farcs1) spectroscopic observations in the 3 m region of the Herbig Ae/Be star HD 97048. For the first time, we spatially resolve the emission in the diamond features at 3.43 and 3.53 m and in the adjacent continuum. Using both the intensity profiles along the slit and reconstructed two-dimensional images of the object, we derive full-width at half-maximum sizes consistent with the predictions for a circumstellar disk seen pole-on. The diamond emission originates in the inner region ( AU) of the disk.- ADAPTIVE OPTICS
