Twins: The Two Shortest Period Non-Interacting Double Degenerate White Dwarf Stars (2009)
Mullally, F., Badenes, Carles, Thompson, Susan E., Lupton, Robert
We report on the detection of the two shortest period non-interacting white dwarf binary systems. These systems, SDSS J143633.29+501026.8 and SDSS J105353.89+520031.0, were identified by searching...
Typing Supernova Remnants Using X-ray Line Emission Morphologies (2009)
Lopez, Laura A., Ramirez-Ruiz, Enrico, Badenes, Carles, Huppenkothen, Daniela, Jeltema, Tesla E., Pooley, David A.
We present a new observational method to type the explosions of young supernova remnants (SNRs). By measuring the morphology of the Chandra X-ray line emission in seventeen Galactic and Large...
Badenes, Carles, Mullally, Fergal, Thompson, Susan E., Lupton, Robert H.
We present the first results from SWARMS (Sloan White dwArf Radial velocity data Mining Survey), an ongoing project to identify compact white dwarf (WD) binaries in the spectroscopic catalog of the...
Badenes, Carles, Harris, Jason, Zaritsky, Dennis, Prieto, Jose Luis
We use the star formation history map of the Large Magellanic Cloud recently published by Harris & Zaritsky to study the sites of the eight smallest (and presumably youngest) supernova remnants in...
Badenes, Carles, Bravo, Eduardo, Hughes, John P.
The Mn to Cr mass ratio in supernova ejecta has recently been proposed as a tracer of Type Ia SN progenitor metallicity. We review the advantages and problems of this observable quantity, and discuss...

We use the star formation history map of the Large Magellanic Cloud recently published by Harris & Zaritsky to study the sites of the youngest Type Ia supernova remnants. We find that most Type Ia...

Badenes, Carles, Bravo, Eduardo, Hughes, John P.
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 Cr mass ratio in...
Cassam-Chenai, Gamil, Hughes, John P., Reynoso, Estela M., Badenes, Carles, Moffett, David
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 of the supernova...
Badenes, Carles, Hughes, John P., Cassam-Chenai, Gamil, Bravo, Eduardo
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 echo. Our goal is...
Badenes, Carles, Hughes, John P., Bravo, Eduardo, Langer, Norbert
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...

Rakowski, Cara E., Badenes, Carles, Gaensler, B. M., Gelfand, Joseph D., Hughes, John P., Slane, Patrick O.
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 formed this...
Badenes, Carles, Borkowski, Kazimierz J., Hughes, John P., Hwang, Una, Bravo, Eduardo
In this paper we use high quality X-ray observations from XMM-Newton and Chandra to gain new insights into the explosion that originated Tycho's supernova 433 years ago. We perform a detailed...
Una Hwang, J. Martin Laming, Carles Badenes, Fred Berendse, John Blondin, Denis Cioffi, ...
We introduce a million-second observation of the supernova remnant Cassiopeia A with the Chandra X-ray Observatory. The bipolar structure of the Si-rich ejecta (NE jet and SW counterpart) is clearly...
A Million-Second Chandra View of Cassiopeia A (2004)
Hwang, Una, Laming, J. Martin, Badenes, Carles, Berendse, Fred, Blondin, John, Cioffi, Denis, ...
We introduce a million-second observation of the supernova remnant Cassiopeia A with the Chandra X-ray Observatory. The bipolar structure of the Si-rich ejecta (NE jet and SW counterpart) is clearly...
Thermonuclear supernova explosions and their remnants: the case of Tycho (2003)
Badenes, Carles, Bravo, Eduardo, Borkowski, Kazimierz J.
We propose to use the thermal X-ray emission from young supernova remnants (SNRs) originated in Type Ia supernovae (SNe) to extract relevant information concerning the explosion mechanism. We focus...

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...
Prospects for SNIa Explosion Mechanism Identification Through Supernova Remnants (2002)
Badenes, Carles, Bravo, Eduardo
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...
The Imprint of Presupernova Evolution on Supernovae Remnants (2001)
Badenes, Carles, Bravo, Eduardo
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...
