Chandra Proposal Id #05500645

Scientific paper

We propose to obtain spatially resolved spectra of the newborn supernova remnant SNR1987A with the ACIS-S/LETG on Chandra. The spectra will provide sufficient counts in several emission lines so that we can, for the first time, directly measure the velocity of the supernova blast wave through line profiles, and the electron temperature through line ratios, as functions of position. We will develop hydrodynamical models to interpret the dispersed X-ray spectra as well as complementary X-ray imaging data and UV and optical images and spectra from the HST and radio images from the Australia Telescope Compact Array.
