Coronal lines in supernova remnant spectra.
Abstract
The detection of coronal line emission offers the possibility of studying the shock-heated plasma in supernova remnants (SNRs). A search was performed for the 5303-A forbidden Fe XIV coronal line in the SNRs N49 and Vela. The line was detected in the former at an intensity suggesting a plasma temperature in the region of 2 million K. However, a previously proposed detection for the Vela SNR was not confirmed.
