Using radiation transport calculations, we compute the line flux for two 3D explosion models: a near-Chandrasekhar mass delayed detonation and a violent merger of two white dwarfs. Both models are based on solar metallicity zero-age main sequence progenitors. Due to explosive nuclear burning at higher density, the delayed-detonation model synthesises 3.5 times more radioactive 55Fe than the merger model.
