Scientific paper

The double-lobed system DEML316 is a particularly puzzling object. Although it is known to be the remnant of one or more supernovae, the precise nature of the structure remains mysterious. Suggestions to date include (1) the collision of two supernova remnants (SNRs); (2) a supernova explosion into a bipolar cavity; or (3) two SNRs superposed along the line of sight. To confirm or rule out these scenarios, we are proposing observations of this system with Chandra's ACIS. We will use spatially-resolved spectroscopy to determine where the hot gas is located within the shells and discover the pattern of temperature variations across the system. The resolution of this puzzle will add greatly to our knowledge of the frequency, distribution, and evolution of SNRs.
