The End of Amnesia: A New Method for Measuring the Metallicity of Type Ia Supernova Progenitors Using Manganese Lines in Supernova Remnants
Carles Badenes, Eduardo Bravo, John P. Hughes
We propose a new method to measure the metallicity of Type Ia supernova progenitors using Mn and Cr lines in the X-ray spectra of young supernova remnants. We show that the Mn to C…
Morphological evidence for azimuthal variations of the cosmic ray ion acceleration at the blast wave of SN 1006
Gamil Cassam-Chenai, John P. Hughes, Estela M. Reynoso +2
Using radio, X-ray and optical observations, we present evidence for morphological changes due to efficient cosmic ray ion acceleration in the structure of the southeastern region…
The Persistence of Memory, or How the X-Ray Spectrum of SNR 0509-67.5 Reveals the Brightness of its Parent Type Ia Supernova
Carles Badenes, John P. Hughes, Gamil Cassam-Chenai +1
We examine the dynamics and X-ray spectrum of the young Type Ia supernova remnant 0509-67.5 in the context of the recent results obtained from the optical spectroscopy of its light…
A Deep Chandra Observation of Kepler's Supernova Remnant: A Type Ia Event with Circumstellar Interaction
S. P. Reynolds, K. J. Borkowski, U. Hwang +4
We present initial results of a 750 ks Chandra observation of the remnant of Kepler's supernova of AD 1604. The strength and prominence of iron emission, together with the absence…
Are the Models for Type Ia Supernova Progenitors Consistent with the Properties of Supernova Remnants?
Carles Badenes, John P. Hughes, Eduardo Bravo +1
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 model…
Can Ejecta-Dominated Supernova Remnants be Typed from their X-ray Spectra? The Case of G337.2-0.7
Cara E. Rakowski, Carles Badenes, B. M. Gaensler +3
In this paper we use recent X-ray and radio observations of the ejecta-rich Galactic supernova remnant (SNR) G337.2-0.7 to determine properties of the supernova (SN) explosion that…
