This study investigates the evolution of Rayleigh-Taylor (R-T) instabilities in Type Ia supernova remnants that are associated with a low adiabatic index γ, where γ < 5/3, which reflects the expected change in the supernova shock structure as a result of cosmic ray particle acceleration. Extreme cases, such as the case with the maximum compression ratio that corresponds to γ = 1.1, are examined. As γ decreases, the shock compression ratio rises, and an increasingly narrow intershock region with… 
Two-dimensional magnetohydrodynamics simulations of young Type Ia supernova remnants
Using two-dimensional magnetohydrodynamics (MHD) simulations, we investigate the dynamical properties of Type Ia supernova remnants (SNRs) evolved either in a uniform ambient medium or from an
Evolutions of Young Type Ia Supernova Remnants with Two Initial Density Profiles in a Turbulent Medium
The expansion index and relative contact discontinuity positions of young type Ia supernova remnants (SNRs) evolving in a turbulent medium are investigated via implementing two-dimensional
Modeling supernova remnants: effects of diffusive cosmic-ray acceleration on the evolution and application to observations
We present numerical models for supernova remnant evolution, using a new version of the hydrodynamical code SUPREMNA. We added a cosmic-ray diffusion equation to the code scheme, employing a
Shock corrugation by Rayleigh-Taylor instability in gamma-ray burst afterglow jets
Afterglow jets are Rayleigh-Taylor unstable and therefore turbulent during the early part of their deceleration. There are also several processes which actively cool the jet. In this Letter, we
Role of Ejecta Clumping and Back-reaction of Accelerated Cosmic Rays in the Evolution of Type Ia Supernova Remnants
We investigate the role played by initial clumping of ejecta and by efficient acceleration of cosmic rays (CRs) in determining the density structure of the post-shock region of a Type Ia supernova
Three-dimensional magnetohydrodynamic studies of the non-thermal X-ray morphologies of SN 1006
Context. The observations of the synchrotron emission from the supernova remnant (SNR) SN 1006 indicate a bilateral morphology, which is mainly characterized by two opposite bright limbs with knots
On Silicon Group Elements Ejected by Supernovae Type Ia
There is evidence that the peak brightness of a Type Ia supernova is affected by the electron fraction Y-e at the time of the explosion. The electron fraction is set by the aboriginal composition of
Vela Jr.: Ejecta-Clump Interaction in the Vela Supernova Remnant
The ROSAT source RX J0852.0-4622, or Vela Jr., superposed on the Vela supernova remnant, has been iden- tified as a separate young supernova remnant based on its shell-like appearance in X-ray > 1.3
Rayleigh-Taylor instability in non-uniform magnetized rotating strongly coupled viscoelastic fluid
The Rayleigh-Taylor instability(RTI) in an incompressible strongly coupled viscoelastic fluid is investigated considering the effects of inhomogeneous magnetic field, density gradient, and uniform
