Infrared emission from 6.7-GHz methanol maser sources.

GOEDHART S., VAN DER WALT D.J. and SCHUTTE A.J.

Abstract (from CDS):

Near-infrared photometry was performed on 56 southern 6.7-GHz methanol maser sources. A simple spherically symmetric model of the radiative transfer through a dust shell was developed and used to study the conditions in the dust cloud in which the masers are produced. The parameters investigated were the size of the cloud, the spectral type of the embedded star, the optical depth of the dust cloud and the dust density distribution. It was found that the infrared colours of the models have a complex dependence on the parameters and that no unique combination of parameter values explains the spectral energy distribution of any particular source. The model effectively reproduces the far-infrared (IRAS) colours but cannot simultaneously explain the near-infrared colours for any of the observed sources.
