Type Ia supernovae are responsible for the nucleosynthesis of the iron peak elements and are widely used as standard candles of modern cosmology. It has long been hoped that gamma-ray studies would help clarify our understanding of these explosions, but because of instrumental limitations, those measurements have not been achieved. Most theoretical studies have emphasized the bright gamma-ray lines (Milne, P. et al. 2004), but here we focus on the lowest energy part of the Compton scattered continuum, below 80 keV. This choice is because the upcoming NuSTAR satellite will have large area mirrors that collect and focus photons up to that energy, and will greatly improve the sensitivity over previous instruments. We calculate the spectrum of the W7 supernova model (Nomoto et al. 1984) to determine at what time and to what distance NuSTAR should observe Type Ia supernovae.
