Table 2
Upper half: model parameters and most abundant nuclei of our nuclear network calculations. Lower half: time of B-band maximum after explosion, absolute model magnitudes, Δm15(B), and wavelength and corresponding blueshift velocity where the absorption of the Si ii 6355 Å feature is deepest at B-band maximum.

Notes. The first five models are for ONe WDs with a homogeneous composition of 3% 12C, 60% 16O, and 37% 20Ne by mass. The last model, a homogenous CO WD with equal mass of 12C and 16O, is for comparison.
