Neutral gas in the vicinity of Herbig AeBe stars: What can we learn from red-shifted sodium absorptined. We present here the preliminary results of calculations aimed at exploring under which physical conditions a sizable amount of neutral sodium can survive in the immediate vicinity of such a star. Spectral lines of circumstellar origin of other elements are also discussed.

We also detect a velocity gradient or shift across the methyl cyanide core whose origin could be due to rotation.

We also examine the effects on the observations of viewing angle and show how two well-studied outflows fit into the global picture of jet-molecular cloud interaction. Finally we show evidence for time-dependent ejection of the jet.

Conference proceedings 1996possible connections to planetary systems and stellar astrophysics makes these topics especially broad, appealing to generalists and specialists alike. The CD not only contains papers that could not be printed in the book but allows the authors to include a fair amount of data, often displayed as color images.

Second, we look at the wider cluster population and the statistical occurrence of circumstellar disks detected through the more traditional signature of infrared excess. Both techniques reveal that a large fraction (≈50–80%) of the young stars in the Trapezium Cluster are likely surrounded by disks.
