SPI Analysis and Abundance Calculations of DEM L71, and Comparison to SN explosion Models
Jared Siegel, Vikram V. Dwarkadas, Kari Frank +2
We analyze the X-Ray emission from the supernova remnant DEM L71 using the Smoothed Particle Inference (SPI) technique. The high Fe abundance found appears to confirm the Type Ia o…
