A Model for the Maser Source NGC 7538 IRS 1
Conference paper
Abstract
High resolution observations of the molecular cloud around NGC 7538 IRS 1 in the J=1-0 transition of 13CO show that the lower bound for density in that region is about 2 x 103 cm-3. The study of various molecular transitions and the continuum measurements of the H II region indicate that the conditions required by the Boland and de Jong model for the excitation of the H2CO maser are not very stringent or unique.
