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 progenitors in the single-degenerate scenario predict substantial outflows during the presupernova evolution. Expanding on previous work, we estimate the imprint of these outflows on the structure of the circumstellar medium at the time of the supernova explosion, and the effect that this modified circumstellar medium has on the evolution of the ensuing supernova remnant. We compare our simulations with the observational properties of known Type Ia supernova remnants in the Galaxy (Kepler, Tycho, SN 1006), the Large Magellanic Cloud (0509-67.5, 0519-69.0, N103B), and M31 (SN 1885). We find that optically thick outflows from the white dwarf surface (sometimes known as "accretion winds") with velocities above 200 km s-1 excavate large low-density cavities around the progenitors. Such large cavities are incompatible with the dynamics of the forward shock and the X-ray emission from the shocked ejecta in all the Type Ia remnants that we have examined.

Characterizing Supernova Progenitors via the Metallicities of their Host Galaxies, from Poor Dwarfs to Rich Spirals (2007, background): “Interestingly, modeling the X-ray spectra of supernova remnants from probable SN Ia explosions in our Galaxy, the LMC, and M31, Badenes et al. (2007) did not find the strong effects of white dwarf winds predicted from theory.”
Observational Clues to the Progenitors of Type Ia Supernovae (2013, background): “In fact, Badenes et al. (2007) find that line fluxes and energy centroids in the X-ray spectra, and the observed radii of the forward shocks, at the known ages of the remnants, are always as expected for ejecta advancing through a uniform-density ISM of ncsm ≈ 1 cm−3.”
Delay Time Distribution Measurement of Type Ia Supernovae by the Subaru/XMM-Newton Deep Survey and Implications for the Progenitor (2008, unknown): “There are some implications for the progenitor from studies of SN Ia remnants (Ruiz-Lapuente et al. 2004; Badenes et al. 2007; Ihara et al. 2007), or from spectroscopic studies (Leonard 2007; Patat et al. 2007a, b; Simon et al. 2007) and archival progenitor searches (Voss & Nelemans 2008; Nelemans…”
SUB-CHANDRASEKHAR WHITE DWARF MERGERS AS THE PROGENITORS OF TYPE Ia SUPERNOVAE (2010, background): “A separate clue is that most remnants appear to be evolving into a constant-density medium, with properties like those of the warm interstellar phase, and unlike those expected for progenitors with strong, fast winds (Badenes et al. 2007).”
Type-Ia Supernova Rates and the Progenitor Problem: A Review (2011, background): “Badenes et al. (2007) searched seven young SN Ia remnants for the wind-blown cavities that would be expected in the wind-regulation picture.”
EVLA OBSERVATIONS CONSTRAIN THE ENVIRONMENT AND PROGENITOR SYSTEM OF Type Ia SUPERNOVA 2011fe (2012, background): “Similar constraints can be drawn from the morphology and X-ray emission of historical supernova remnants (SNRs) of Type Ia origin.”
Constraining the Type Ia Supernova Progenitor: The Search for Hydrogen in Nebular Spectra (2006, background): “Observational doubt on accretionwinds playing a major role in pre-SN Ia evolution is cast by Badenes et al. (2007), who find that such an optically thick outflow from aWD’s surface should excavate a large, low-density cavity around the system.”
NORMAL TYPE Ia SUPERNOVAE FROM VIOLENT MERGERS OF WHITE DWARF BINARIES (2012, background): “…emission of SNe Ia (e.g. Hancock et al. 2011), the lack of hydrogen emission in nebular spectra of SNe Ia (Leonard 2007), the lack of X-ray emission in elliptical galaxies (Gilfanov & Bogdán 2010) and studies of SN Ia remnants (e.g. Badenes et al. 2007) seem to favor the double degenerate scenario.”
