----- Attempting Submission 1 (Fri Oct 23 19:10:44 GMT 2009) ----- The Proper Motion of SNR E0519-69.0 We propose to measure independently the proper motion expansions of the ejecta and forward shock in SNR E0519-69.0. The metal-enriched reverse-shock-heated ejecta emits only in X-rays, while the forward shock is traced to high precision by H alpha emission. The proposed measurements require the unique high resolution imaging capabilities of Chandra and Hubble. The optical (forward shock) and X-ray (ejecta) results will yield important constraints on the remnant's evolutionary state; we will search in particular for evidence of cosmic-ray modified dynamics. An important component of this project is an integrated theoretical investigation using realistic models of SN Ia explosions evolved to the remnant stage.
This is a program to image a small (approx. 30 arcsec diameter), nearly round supernova remnant in H alpha in order to accurately locate, and measure the expansion rate of, the forward shock. The radial expansion rate of the rim is estimated to be between 0.01 and 0.03 arcsec per year. We will use the ACS WFC with the F658N filter. The expansion measurement requires that the observation be split in two with a time interval between exposures of roughly 1 year and the same observation orientation. We will also take contemporaneous images of the stellar field using the F550M filter.
