摘要：

We present the analysis of FUSE observations of two Herbig AeBe stars known to harbor young circumstellar disks: HD100546 and HD163296. In both cases we detect absorption lines from warm and dense H-2. The thermalization of the rotational levels up to Jsimilar to4 allows evaluation of the temperature, density and typical size of the absorbing layer. These quantities are consistent with absorption of the light of the central star by a thin layer of a circumstellar disk seen at an intermediate inclination.
