Scientific paper

Fe XIV coronal forbidden line emission from the supernova remnant Puppis-A was spectroscopically detected. Two-dimensional spectral data imply that the approximately 10 to the 6th K plasma coronal-line component forms a halo surrounding the cooler approximately 10 to the 4th K optical filamentary component, suggesting that it originates from evaporated plasma from dense cloudlets rather than swept-up interstellar material. This result influences the interpretation of X-ray emission from supernova remnants.
