Spatially and spectrally resolved 10 μm emission in Herbig Ae/Be stars
2004
Astronomy and Astrophysics
We present new mid-infrared spectroscopy of the emission from warm circumstellar dust grains in the Herbig Ae stars HD 100546, HD 97048 and HD 104237, with a spatial resolution of ≈0. 9. We find that the emission in the UIR bands at 8.6, 11.3 and (HD 97048 only) 12.7 µm is extended in the first two sources. The continuum emission is resolved in HD 97048 and possibly in HD 100546. HD 104237 is not spatially resolved in our observations. We find that the UIR emission in HD 100546 and HD 97048 is
