Abstract
Recent studies using the Very Large Array (VLA) telescope have revealed the existence of two unusual extended non-thermal sources, G357.7–0.1 and G5.3–1.0 (refs 1,2). Classified earlier as supernova remnants (SNRs), these sources have a marked axial symmetry and compact sources on the axis at one edge. We have now looked for counterparts of these sources in the Infrared Astronomical Satellite (IRAS) Point Source Catalogue and find an IRAS source showing the characteristic spectrum of an early type star embedded in a dusty cloud, coincident with the compact source in G357.7–0.1. We propose that the compact object is an O star whose formation was triggered by the shock front of the diffuse radio source.
