We present adaptive optics high angular resolution (~0.1") spectroscopic observations in the 3 μm 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 μm and in the adjacent continuum. Using both the intensity profiles along the slit and reconstructed two-dimensional images of the object, we derive FWHM sizes consistent with the predictions for a circumstellar disk seen pole-on. The diamond emission originates in the inner region (R<~15 AU) of the disk.

Abstract
We present adaptive optics high angular resolution (~0.1") spectroscopic observations in the 3 μm 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 μm and in the adjacent continuum. Using both the intensity profiles along the slit and reconstructed two-dimensional images of the object, we derive FWHM sizes consistent with the predictions for a circumstellar disk seen pole-on. The diamond emission originates in the inner region (R<~15 AU) of the disk.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
