Detection of the Fe XIV 5303 A coronal line in the supernova remnant Vela X

  • 1. Columbia Astrophysics Laboratory, Columbia University, New York

Description

The coronal line Fe xiv 5303 A has been detected in Vela X at a statistical significance above zero of 6.3 sigma with a flux (3.9 +- 0.6) x 10-12 ergs (cm2 s)-1 in a 10 diameter field. This demonstrates that the X-ray flux of Vela X is of thermal origin. The 3 sigma upper limits for the Fe xiv 5303 A and Ar xiv 4412 A coronal line fluxes from the supernova remnant Puppis A are respectively 4 x 10-12 and 2.6 x 10-12 ergs (cm2 s)-1
