Type Ia supernovae (SNe) are presumed to arise from white dwarf progenitors, which may not appreciably modify their ambient medium. We study the interaction of the resulting supernova remnants with a constant density interstellar medium. Density profiles obtained from detailed explosion models of Type Ia SN explosions can be complex, but an exponential profile gives the best approximate representation of a set of profiles, and we emphasize this case. We describe the time evolution of dynamical…

The Interaction of Type Ia Supernovae with their Surroundings: The Exponential profile in 2D
The evolution of Type Ia supernovae in the surrounding medium is studied using 2-dimensional numerical hydrodynamic simulations. The ejecta are assumed to be described by an exponential density
Signatures of the circumstellar environment in a normal type Ia supernova
We present observations of the Type Ia supernova 2003du obtained with the Hobby-Eberly Telescope and report the detection of a high-velocity component in the Ca II infrared triplet near 8000 A,

Abstract Supernova remnants are the site of a number of physical processes (shock-heating, non-equilibrium ionization, hydrodynamic instabilities, particle acceleration, magnetic field
Hydrodynamics of Young Supernova Remnants and the Implications for their Gamma-ray emission
Supernovae (SNe) are generally classified into Type I and Type II. Most SNe (~ 80%), including all the subtypes of Type II, and Type Ib/c, arise from the core-collapse of massive stars. During their
Modelling the interaction of thermonuclear supernova remnants with circumstellar structures: the case of Tycho's supernova remnant
The well-established Type Ia remnant of Tycho's supernova (SN 1572) reveals discrepant ambient medium-density estimates based on either the measured dynamics or the X-ray emission properties. This
Thermal X-Ray Emission from Shocked Ejecta in Type Ia Supernova Remnants. II. Parameters Affecting the Spectrum
The supernova remnants (SNRs) left behind by Type Ia supernovae (SNe) provide an excellent opportunity for the study of these enigmatic objects. In a previous work we showed that it is possible to
The Imprint of Presupernova Evolution on Supernova Remnants
The evolution of Type Ia supernova binary system progenitors is highly uncertain. Several evolutionary models predict that the accretion of mass onto the white dwarf is accompanied by mass ejection
Dark Age of Type II Supernova Remnants
Supernova remnants (SNRs) are important objects in terms of their connections with supernova (SN) explosion mechanism(s), progenitor stars, and cosmic-ray acceleration. Nonthermal emission from SNRs
Constraints on the physics of type ia supernovae from the x-ray spectrum of the tycho supernova remnant
We explore the relationship between the models for progenitor systems of Type Ia supernovae and the properties of the supernova remnants that evolve after the explosion. Most models for Type Ia
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


Are young supernova remnants interacting with circumstellar gas
The young remnants of galactic Type I supernovae (SN 1006, SN 1572, and SN 1604) appear to be interacting with moderately dense gas (n/sub O/> or =0.1 cm/sup -3/). If the gas in the ambient
The Evolution of Young Supernova Remnants
Einstein X-ray observations of the young supernova remnants Cassiopeia A (Murray et al. 1980) and Tycho (Seward, Gorenstein and Tucker 1982) indicate that the swept-up mass does not much exceed that
A new similarity solution for reverse shocks in supernova remnants
A new self-similar solution is presented for the early time development of a reverse shock propagating into supernova ejecta with an initially uniform density. The ejecta are taken to be expanding
Circumstellar Hα from SN 1994D and future Type Ia supernovae: an observational test of progenitor models
Searching for the presence of circumstellar material is currently the only direct way to discriminate between the different types of possible progenitor systems for Type Ia supernovae. We have
We review the candidate progenitor binary systems of Type Ia supernovae (SNe Ia). We argue that the exploding star is likely to be a mass accreting carbon-oxygen white dwarf. "Primary"
The distribution of interstellar matter toward Tycho's supernova remnant and its relation to distance estimates
Observations of interstellar absorption lines in the spectra of five stars in the direction of Tycho's Supernova Remnant are presented. The profiles show significant absorption at large negative
The X-ray spectrum of SN 1006
The supernova (SN) of A.D. 1006 represents the brightest in recorded history. The X-ray observations of its remnant appear to be full of puzzles. The present paper has the objective to reevaluate
The mass of Tycho's supernova remnant as determined from a high-resolution X-ray map.
High resolution Einstein Observatory X ray images of Tycho's supernova remnant (SNR) are discussed. The object has features of a shock heated shell in the interstellar medium, accompanied by an inner
