On the Circumstellar Matter Distribution around Herbig Ae/Be Stars

摘要

The spectral energy distributions (SEDs) observed in Herbig Ae/Be stars are critically analyzed in connection with a spherically symmetric model for matter distribution around the central objects. The possibility that the dusty component is described by an MRN-DL mixture (see the work of Mathis, Rumpl, and Nordsiek; Draine and Lee) and is constituted by particles with mean sizes greater than those typical of the interstellar medium is considered.
