R. ; Keenan, D. W. Abstract An attempt has been made to identify very young planetary nebulae from radio observations. Details of the observations at the Algonquin Radio Observatory and the Very Large Array are presented. Four nebulae which were previously designated as stellar are resolved using aperture synthesis techniques with angular resolution as high as 0.2 arcsec. Two of the observed nebulae, SwSt-1 and M3-38, exhibit characteristics expected of very young planetary nebulae. These two nebulae are compared to other planetary nebulae which are believed to be young, and the possibility that young planetary nebulae may have different spectral behavior in the radio is discussed.
