Title: BLAST WAVE DYNAMICS, SUPERNOVA REMNANT ENVIRONMENTS, AND THE EVOLUTION OF THE CYGNUS LOOP
Observer: Graham
Subject Category: SN, SNR, and isolated NS
Seq: 500029 ObsId: 00733
Long-term Plan bin: 13-Mar-2000
ABSTRACT
The Cygnus Loop, as the closest, brightest, and best-studied example of its class, is the prototypical shell supernova remnant (SNR). SNR evolution is complex because the interstellar medium is inhomogeneous and modified by the supernova progenitor. We propose to study the interaction of the Cygnus Loop with its environment and hence elucidate its evolution. X-ray spectroscopy provides the best tools to quantify the conditions and the microscopic and macroscopic processes that determine the balance between heating and cooling in shocked gas. AXAF provides revolutionary capabilities because it offers the first opportunity to obtain imaging spectroscopy with the combined spatial and spectral resolution necessary to measure plasma properties on scales relevant to blast wave gas-dynamics.
