VLA radio maps at 5-GHz of the G10.2-0.3 H II region in the W31 complex reveal an extended ionization ridge of dimensions 5.7×2.9 pc2 at an assumed distance of 7 kpc. In the ridge the authors have found 21 dense clumps with characteristic emission measures of ≡106pc cm-6 and electron densities ne > 103cm-3, suggesting embedded stars. From estimates of the number of Lyman continuum photons required to support the radio structure, the authors find spectral types in the ridge which range from B0.5 to O6. The observed radio structure cannot be explained by excitation from a single embedded source, or by expansion of shock-heated gas into the interstellar medium.
