Revised observing plan to correct errors in POS-TARG values, which were all
set equal, for the first 6 exposures of visit 2. Now the POS-TARG values are
different as required for proper dithering. ----- Attempting Submission 5 (Fri Aug 31 22:05:10 GMT 2007) -----

The Proper Motion of Supernova Remnant E0509-67.5We propose to measure independently the proper motion expansions of the ejecta and forward shock in E0509-67.5. 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 of the remnant is estimated to be 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.12false0.0falsefalsefalsefalsefalsefalseSUPPORTEDISMSNR1.2e-16 erg/cm^2/s/arcsec^2; mean H alpha surface brightness of targetJ200000 00 0.0000+00 00 0.00J2000POS-TARGDITHER0.265LINE0.187falsefalse69.050003420.67ACS-WFC-DITHER-BOX1false
