Table 1

Summary of results of the simulated explosions of hybrid-core CONe WDs.

Notes.

^(a)

Burning mode: DETO = pure detonation; DDT = delayed detonation.

^(b)

Density of deflagration-to-detonation transition in DDT models in 10⁷ g cm^-3.

^(c)

This column and the next two give the ejected mass of ⁵⁶Ni, intermediate-mass elements (IME), and iron-group elements (IGE), respectively.

^(d)

Kinetic energy of the ejecta (1 foe = 10⁵¹ erg).

^(e)

Initial abundance of X(¹²C) set to 0.02 outside M_CO.

^(f)

WD born with hybrid core, but mixed during carbon simmering.

^(g)

Model with X(¹²C) = 0.10, representative of the result of the mixing between hybrid cores with M_CO within the range given in column two and a mantle with its default composition, X_out(¹⁶O) = 0.37 and X_out(²⁰Ne) = 0.63.

^(h)

Model with X(¹²C) = 0.20, representative of the result of the mixing between hybrid cores with M_CO within the range given in column two and a mantle formed by two layers, an inner layer with the default composition and an external layer that is rich in carbon, X_ext(¹²C) = 0.32, with a mass M_ext = 0.57M_⊙.

⁽ⁱ⁾

Initial composition obtained by full mixing of that of the initial model of ID 22 (and ID 23).
