| Popis: | We have modeled the observed spectral energy distributions (SEDs) of young stellar objects (YSOs) in giant molecular clouds (GMCs). We propose the theoretical models for the dust envelopes around YSOs. The YSOs in a GMC may share the same initial chemical composition. In this paper, we compare the model SEDs with the observations of the YSOs. Dust shells of the YSOs are composed of a mixture of astronomical silicate and graphite grains. We propose the models for the evolution of the GMCs comparing the shape of the SEDs on the IRAS 2-color diagram with the age. |
