We present preliminary results of a project to calculate the integrated X-ray spectrum of a supernova remnant (SNR) over its lifetime. The integrated spectra can serve as tools for understanding the detailed time-dependent X-ray emission from SNRs and can also be used to derive an integrated galactic surface brightness from a population of SNRs in a galaxy. The expected galactic surface brightness can then be compared to measurements from X-ray telescopes such as ROSAT, placing firm limits on the population of evolving SNRs in the galaxy and their interstellar environments.
We integrate the X-ray emission from spherical SNR hydrodynamical models, following the complete non-equilibrium ion abundance evolution, over a wide range of ambient interstellar densities and magnetic field strengths. The hydrodynamical code also includes the effects of a one-dimensional non-thermal magnetic pressure, electron thermal conduction, and dynamic elemental depletions from dust sputtering.
