Scientific paper

We propose a deep Chandra observation of the Balmer-dominated SNR, DEM L71, to unambigously constrain the electron temperature immediately behind the blastwave, at locations of varying shock speed. Combined with the proton temperature derived from our existing Halpha spectra, we will determine the degree of electron-proton temperature equilibration at the shock front. We will use an ACS WFC Halpha image to localize the position of the blastwave to 0.1(arcsec) and thereby constrain the shock geometry, a critical component in fitting the blastwave X-ray spectra. An ACS WFC [O III] image will identify regions to avoid in our X-ray spectral analysis, where the onset of radiative cooling behind the shock invalidates the interpretation of our Halpha spectra.
