SN Ia DDT Explosions Powered by the Zeldovich Reactivity Gradient Mechanism
Ezra Brooker, Tomasz Plewa, Daniel Fenn
The aim of this work is to identify and explain the necessary conditions required for an energetic explosion of a Chandrasekhar-mass white dwarf. We construct and analyze weakly co…
Interaction of hemispherical blast waves with inhomogeneous spheres: Probing the collision of a supernova ejecta with a nearby companion star in the laboratory
Domingo García-Senz, Pedro Velarde, Francisco Suzuki-Vidal +5
Past high-energy density laboratory experiments provided insights into the physics of supernovae, supernova remnants, and the destruction of interstellar clouds. In a typical exper…
Multidimensional Models of Type Ia Supernova Nebular Spectra: Strong Emission Lines from Stripped Companion Gas Rule Out Classic Single Degenerate Systems
Janos Botyanszki, Daniel Kasen, Tomasz Plewa
The classic single-degenerate model for the progenitors of Type Ia Supernova (SN Ia) predicts that the supernova ejecta should be enriched with solar-like abundance material stripp…
Detonability of white dwarf plasma: turbulence models at low densities
Daniel Fenn, Tomasz Plewa
We study the conditions required to produce self-sustained detonations in turbulent, carbon-oxygen degenerate plasma at low densities. We perform a series of three-dimensional hydr…
No double detonations but core carbon ignitions in high-resolution, grid-based simulations of binary white dwarf mergers
D. Fenn, T. Plewa, A. Gawryszczak
We study the violent phase of the merger of massive binary white dwarf systems. Our aim is to characterize the conditions for explosive burning to occur, and identify a possible ex…
Toward connecting core-collapse supernova theory with observations: I. Shock revival in a 15 Msun blue supergiant progenitor with SN 1987A energetics
Timothy Handy, Tomasz Plewa, Andrzej Odrzywolek
We study the evolution of the collapsing core of a 15 Msun blue supergiant supernova progenitor from the core bounce until 1.5 seconds later. We present a sample of hydrodynamic mo…
Non-spherical core collapse supernovae III. Evolution towards homology and dependence on the numerical resolution
A. Gawryszczak, J. Guzman, T. Plewa +1
(abridged) We study the hydrodynamic evolution of a non-spherical core-collapse supernova in two spatial dimensions. We find that our model displays a strong tendency to expand tow…
Probing thermonuclear supernova explosions with neutrinos
A. Odrzywolek, T. Plewa
Aims: We present neutrino light curves and energy spectra for two representative type Ia supernova explosion models: a pure deflagration and a delayed detonation. Methods: We calcu…
