Scientific paper

Radio-continuum measurements at several frequencies have been made of eight early-type emission-line stars which possess strong infrared excesses. Of these, two represent new radio detections. The observations were made at 2.7 and 8.1 GHz using the four-element interferometer of NRAO and at 10.6 and 22.2 GHz using the 46-m dish of the Algonquin Radio Observatory. The spectra are in all cases consistent with free-free radiation from a dense circumstellar gas shell. Four of the objects possess spectra suggestive of uniform radial mass outflow
