The explosion mechanism behind Type Ia supernovae is a matter of continuing debate. The diverse attempts to identify or at least constrain the physical processes involved in the explosion have been only partially successful so far. In this paper we propose to use the thermal X-ray emission from young supernova remnants (SNRs) originating in Type Ia events to extract relevant information concerning the explosions themselves. We have produced a grid of thermonuclear supernova models… 
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
Thermal X-Ray Emission From Young Type Ia Supernova Remnants
In the years since the launch of Chandra and XMM-Newton, the increase in the quantity and quality of X-ray observations of supernova remnants (SNRs) has been spectacular. In many of the brightest
Reverse and Forward Shock X-ray Emission in an Evolutionary Model of Supernova Remnants undergoing Efficient Diffusive Shock Acceleration
We present new models for the forward and reverse shock thermal X-ray emission from core-collapse and Type Ia supernova remnants (SNRs) which include the efficient production of cosmic rays via
Observational Evidence for High Neutronization in Supernova Remnants: Implications for Type Ia Supernova Progenitors
The physical process whereby a carbon–oxygen white dwarf explodes as a Type Ia supernova (SN Ia) remains highly uncertain. The degree of neutronization in SN Ia ejecta holds clues to this process
The many sides of RCW 86: a type Ia supernova remnant evolving in its progenitor's wind bubble
We present the results of a detailed investigation of the Galactic supernova remnant RCW 86 using the XMM-Newton X-ray telescope. RCW 86 is the probable remnant of SN 185 A.D., a supernova that
XMM-Newton observations of the supernova remnant IC 443: II. evidence of stellar ejecta in the inner regions.
Aims. We investigate the spatial distribution of the physical and chemical properties of the hot X-ray emitting plasma of the supernova remnant IC 443, in order to get important constraints on its
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

The most relevant results on supernova remnants obtained during the first decade of Chandra and the impact that these results have had on open issues in supernova research are reviewed.
Chandrasekhar and Sub-Chandrasekhar Models for the X-Ray Emission of Type Ia Supernova Remnants. I. Bulk Properties
Type Ia supernovae originate from the explosion of carbon–oxygen white dwarfs in binary systems, but the exact nature of their progenitors remains elusive. The bulk properties of Type Ia supernova
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


The X-Ray Iron Emission from Tycho's Supernova Remnant
We present the results of broadband spectral model fits to the X-ray spectrum of Tycho's supernova remnant obtained by the Solid-State Imaging Spectrometers on the ASCA Observatory. We use single
Interaction of Type Ia Supernovae with Their Surroundings
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
Accelerated Electrons in Cassiopeia A: Thermal and Electromagnetic Effects
We consider in more detail a model previously proposed for the hard X-ray (>10 keV) emission observed from the supernova remnant Cas A, whereby electrons are accelerated by lower hybrid waves and
Supernova Remnants in the Sedov Expansion Phase: Thermal X-Ray Emission
Improved calculations of X-ray spectra for supernova remnants (SNRs) in the Sedov-Taylor phase are reported, which for the first time include reliable atomic data for Fe L-shell lines. This new set
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
Nucleosynthesis and Mixing in Cassiopeia A.
The first unequivocal identification of iron-rich ejecta produced by explosive silicon burning in a young Galactic SNR is made, indicating that bulk motions were extensive and energetic enough in Cas A to cause a spatial inversion of a significant portion of the supernova core.
Prospects for SNIa Explosion Mechanism Identification Through SNRs
We present the first results from an ongoing work aimed to use supernovae remnants to discriminate among different type Ia supernovae explosion models. We have computed the hydrodynamic interaction
