Mesoscale Turbulence in Type Ia Supernova Deflagrations II. Evidence for Fuel Preheat Due to Flame Thermal Expansion from Lagrangian Analysis
Ryan Learn, Andrey Zhiglo, Tomasz Plewa
Thermonuclear flame fronts in Type Ia supernovae develop hydrodynamic instabilities that generate turbulent mesoscale flow and substantial local thermodynamic variability. Recent w…
Imprints of the ejecta-companion interaction in Type Ia supernovae: main sequence, subgiant, and red giant companions
P. Boehner, T. Plewa, N. Langer
We study supernova ejecta-companion interactions in a sample of realistic semidetached binary systems representative of Type Ia supernova progenitor binaries in a single-degenerate…
Non-spherical Core Collapse Supernovae I. Neutrino-Driven Convection, Rayleigh-Taylor Instabilities, and the Formation and Propagation of Metal Clumps
K. Kifonidis, T. Plewa, H. -Th. Janka +1
Two-dimensional simulations of a Type II and a Type Ib-like supernova explosion are presented that encompass shock revival by neutrino heating, neutrino-driven convection, explosiv…
Exploding and Non-exploding Stars: Coupling Nuclear Reaction Networks to Multidimensional Hydrodynamics
K. Kifonidis, T. Plewa, E. Mueller
After decades of one-dimensional nucleosynthesis calculations, the growth of computational resources has meanwhile reached a level, which for the first time allows astrophysicists…
Non-spherical core collapse supernovae and nucleosynthesis
K. Kifonidis, E. Mueller, T. Plewa
Motivated by observations of supernova SN 1987A, various authors have simulated Rayleigh-Taylor (RT) instabilities in the envelopes of core collapse supernovae (for a review, see M…
Convective cores in galactic cooling flows
A. Kritsuk, T. Plewa, E. Mueller
We use hydrodynamic simulations with adaptive grid refinement to study the dependence of hot gas flows in X-ray luminous giant elliptical galaxies on the efficiency of heat supply…
Nucleosynthesis and Clump Formation in a Core Collapse Supernova
K. Kifonidis, T. Plewa, H. -Th. Janka +1
High-resolution two-dimensional simulations were performed for the first five minutes of the evolution of a core collapse supernova explosion in a 15 solar mass blue supergiant pro…
Bending relativistic jets in AGNs
T. Plewa, J. Ma. Marti, E. Mueller +2
We present simulations of relativistic jets propagating in a nonuniform medium. Specifically, we study the bending of jets propagating obliquely to the vector of the density-gradie…
On the evolution of ejecta fragments in compact supernova remnants
R. Cid-Fernandes, T. Plewa, M. Rozyczka +4
We examine the evolution of inhomogeneities (fragments) of supernova ejecta in compact supernova remnants by means of hydrodynamical modeling and simplified analytical calculations…
