Query: Multi-Dimensional Parameter Study of Double Detonation Type Ia
  Supernovae Originating from Thin-Helium-Shell White Dwarfs   Despite the importance of Type Ia supernovae (SNe Ia) throughout astronomy,
the precise progenitor systems and explosion mechanisms that drive SNe Ia are
still unknown. An explosion scenario that has gained traction recently is the
double detonation in which an accreted shell of He detonates and triggers a
secondary detonation in the underlying white dwarf. Our research presents a
number of high resolution, multi-dimensional, full star simulations of
thin-He-shell, sub-Chandrasekhar-mass white dwarf progenitors that undergo a
double detonation. This suite of thin-shell progenitors incorporates He shells
that are thinner than those in previous multi-dimensional studies. We confirm
the viability of the double detonation across a range of He shell parameter
space as well as present bulk yields and ejecta profiles for each progenitor.
The yields obtained are generally consistent with previous works and indicate
the likelihood of producing observables that resemble SNe Ia. The
dimensionality of our simulations allow us to examine features of the double
detonation more closely, including the details of the off-center secondary
ignition and asymmetric ejecta. We find considerable differences in the
high-velocity extent of post-detonation products across different lines of
sight. The data from this work will be used to generate predicted observables
and may further support the viability of the double detonation scenario as a
SNe Ia channel as well as show how properties of the progenitor or viewing
angle may influence trends in observable characteristics.
