The Evolution Of Cosmic Ray Mediated Mhd Shocks : A Two-Fluid Approach (2008)
Byung-Il Jun, David A. Clarke, Michael L. Norman
We study the shock structure and acceleration efficiency of cosmic ray mediated MHD shocks both analytically and numerically by using a two-fluid model. Our model includes the dynamical effect of...
We present two-dimensional MHD simulations of the evolution of a young Type Ia supernova remnant during its interaction with an interstellar cloud of comparable size at impact. We include for the...
Interaction of a Pulsar Wind with the Expanding Supernova Remnant (1997)
Recent HST observations of the Crab Nebula show filamentary structures that appear to originate from the Rayleigh-Taylor (R-T) instability operating on the supernova ejecta accelerated by the...
$10^{51}$ Ergs: The Evolution of Shell Supernova Remnants (1997)
Jones, T. W., Rudnick, Lawrence, Jun, Byung-Il, Borkowski, Kazimierz J., Dubner, Gloria, Frail, Dale A., ...
This paper reports on a workshop hosted by the University of Minnesota, March 23-26, 1997. It addressed fundamental dynamical issues associated with the evolution of shell supernova remnants and the...
The Density Spike in Cosmic-Ray-Modified Shocks: Formation, Evolution, and Instability (1996)
We examine the formation and evolution of the density enhancement (density spike) that appears downstream of strong, cosmic-ray-modified shocks. This feature results from temporary overcompression of...
Interaction of Rayleigh-Taylor Fingers and Circumstellar Clodlets in Young Supernova Remnants (1996)
Jun, Byung-Il, Jones, T. W., Norman, Michael L.
We discover a new dynamical mechanism that significantly enhances the growth of Rayleigh-Taylor fingers developed near the contact interface between the supernova ejecta and swept-up ambient gas in...
On the Origin of Radial Magnetic Fields in Young Supernova Remnants (1996)
Jun, Byung-Il, Norman, Michael L.
We study the radio emission from young supernova remnants by means of 3D numerical MHD simulations of the Rayleigh-Taylor instability in the shell of the remnant. The computation is carried out in...
On the Origin of Strong Magnetic Fields in Young Supernova Remnants (1996)
Jun, Byung-Il, Norman, Michael L.
Young supernova remnants such as Tycho generally exhibit a bright circular clumpy shell in both radio and X-ray emission. For several young remnants, various arguments suggest that the magnetic field...
