Synthetic spectra for the SN Ia model DDC15 with 0.18 M of stripped material. We show the total emergent luminosity Lλ as well as that associated with the continuum and bound-bound transition of selected ions (H I, He I, O I, and Ca II). The calculations for the latter are done by assuming that only the selected ion contributes (together with all continuum processes) and thus ignore the impact of other ions on that selected ion (such as metal-line blanketing on the H I lines arising from the innermost regions associated with the stripped material). The other three models show a similar behavior to that shown here for model DDC15. Hence, while the stripped, low-velocity material is expected to radiate quite strongly at many wavelengths, the primary observable feature at optical wavelengths is due to Hα.
