A Tale of Two Remnants: A Comparative Study of the Young Ia SNRs 0509-67.5 and 0519-69.0 We propose deep observations of two young supernova remnants in the LMC, 0509-67.5 and 0519-69.0. Both are remnants of Type Ia supernovae. Along with three complementary HST orbits, we will compare and contrast these two objects, exploring the nature of Type Ia supernova explosions and particle acceleration in the fast shock waves present. Our observations will locate the supernova ejecta products and measure their abundances, both key discriminators in various explosion models. We will measure or put limits on the expansion of both remnants. This is a single filter image of a small target (30" diameter) with the F657N filter, using 3 orbits.
