Walk beneath the silver moon;

In science:

Their result, which springs from detailed SNIa modelling, is stable against variations in the initial conditions and explosion mechanisms (either delayed detonation or deflagr ation) of the models explored.
Manganese evolution in Omega Centauri: a clue to the cluster formation mechanisms?
This result is consistent with predictions for the double degenerate SN Ia progenitor scenario (s ∼ −1), and is also in line with recent calculations for the double detonation explosion mechanism (s ∼ −2).
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
Finally there is the double detonation scenario, a specific variant of the SD scenario, in which an outer He-burning shell, being fed from a companion, undergoes several flashes (e.g.
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
Comparison with theoretical predictions As touched on in § 1, there are currently three major progenitor/explosion paths to SNe Ia; the SD scenario, the DD scenario and the double detonation scenario.
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
Recently, Ruiter et al. (2011) determined the DTD for the double detonation scenario, and found a power law falloff with Ψ ∝ t−2 .
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
To conclude, our late-time DTD measurement is in broad agreement with recent binary population synthesis calculations for the double detonation scenario, and is only ∼ 1σ discrepant from expectations for the DD scenario.
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
This DTD is consistent with both the DD and double detonation scenarios for the SN Ia progenitor.

We also plot the best-fitting t−1 and t−2 power laws for illustrative purposes, as these are the expected power law forms for the double degenerate and double detonation scenarios, respectively.
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
We base our discussion on three-dimensional simulations of a delayed detonation in a Chandrasekhar-mass white dwarf and of a violent merger of two white dwarfs—realizations of explosion models appropriate for two of the most widely-discussed progenitor channels that may give rise to SNe Ia.
Constraining Type Ia supernova models: SN 2011fe as a test case
Here, we address the question of whether SN 2011fe can be explained by models of an exploding Chandrasekharmass WD (realized as a delayed detonation) or a violent merger of two WDs.
Constraining Type Ia supernova models: SN 2011fe as a test case
The most promising way of producing observables in reasonable agreement with observations of normal SNe Ia from an explosion of a Chandrasekhar-mass WD is the delayed detonation mechanism (Khokhlov 1991).
Constraining Type Ia supernova models: SN 2011fe as a test case
Since the initiation of a detonation proceeds on scales that are not resolved in our simulations, the probability of finding high turbulent velocities on unresolved scales is extrapolated applying the procedure of R¨opke (2007).
Constraining Type Ia supernova models: SN 2011fe as a test case
This model, called N100, is part of a larger set of delayed-detonation simulations (Seitenzahl et al., in preparation).
Constraining Type Ia supernova models: SN 2011fe as a test case
While the inspiral and merger phases were followed with a version of the SPH code Gadget (Springel 2005), the subsequent thermonuclear detonation was modeled with techniques similar to those employed in N100.
Constraining Type Ia supernova models: SN 2011fe as a test case
The question of whether a detonation triggers at the interface between the two merging stars is controversial.
