摘要
A multi-wavelength investigation of the candidate supernova remnant G63.7+1.1 and its surrounding interstellar medium is presented. On the basis of radio continuum data we conclude that the object is a filled-center supernova remnant, perhaps in the course of becoming a composite remnant. The morphology of the remnant, along with H I, (CO)-C-12, and high resolution IRAS data, suggest that G63.7+1.1 is interacting directly with the ISM, and does not lie in a low density region of the ISM. This in turn strongly suggests that the detected nebula is not surrounded by an invisible halo of supernova ejecta. The association between the SNR and HI and CO features near the tangent point implies a kinematic distance for G63.7+1.1 of 3.8+/-1.5 kpc. (C) 1997 American Astronomical Society.
