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...
Pulsating reverse detonation models of Type Ia supernovae. I: Detonation ignition (2009)
Bravo, Eduardo, Garcia-Senz, Domingo
Observational evidences point to a common explosion mechanism of Type Ia supernovae based on a delayed detonation of a white dwarf. Although several scenarios have been proposed and explored by means...
Pulsating reverse detonation models of Type Ia supernovae. II: Explosion (2009)
Bravo, Eduardo, Garcia-Senz, Domingo, Cabezon, Ruben M., Dominguez, Inmaculada
Observational evidences point to a common explosion mechanism of Type Ia supernovae based on a delayed detonation of a white dwarf. However, all attempts to find a convincing ignition mechanism based...

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...
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...
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...
A Three-Dimensional Picture of the Delayed-Detonation Model of Type Ia Supernovae (2007)
Bravo, Eduardo, Garcia-Senz, Domingo
Deflagration models poorly explain the observed diversity of SNIa. Current multidimensional simulations of SNIa predict a significant amount of, so far unobserved, carbon and oxygen moving at low...
Detailed Spectral Modeling of a 3-D Pulsating Reverse Detonation Model: Too Much Nickel (2007)
Baron, E., Jeffery, David J., Branch, David, Bravo, Eduardo, Garcia-Senz, Domingo, Hauschildt, Peter H.
We calculate detailed NLTE synthetic spectra of a Pulsating Reverse Detonation (PRD) model, a novel explosion mechanism for Type Ia supernovae. While the hydro models are calculated in 3-D, the...
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...
Beyond the bubble catastrophe of Type Ia supernovae: Pulsating Reverse Detonation models (2006)
Bravo, Eduardo, Garcia-Senz, Domingo
We describe a mechanism by which a failed deflagration of a Chandrasekhar-mass carbon-oxygen white dwarf can turn into a successful thermonuclear supernova explosion, without invoking an ad hoc...
Neuroanatomical basis of behavioral disturbances in patients with prefrontal lesions (2006)
Slachevsky C., Andrea, Peña, Marcela, Pérez, Carolina, Bravo, Eduardo, Alegría, Patricia
The role of the frontal lobe in control of behavioral and cognitive abilities is explored in a group of 34 patients with brain lesions restricted to the prefrontal cortex. The scores in both...
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...
Explosion models for thermonuclear supernovae resulting from different ignition conditions (2004)
Bravo, Eduardo, Garcia-Senz, Domingo
We have explored in three dimensions the fate of a massive white dwarf as a function of different initial locations of carbon ignition, with the aid of a SPH code. The calculated models cover a...
High temperature combustion: Approaching equilibrium using nuclear networks (2004)
Gomez, Ruben M. Cabezon, Garcia-Senz, Domingo, Bravo, Eduardo
A method for integrating the chemical equations associated with nuclear combustion at high temperature is presented and extensively checked. Following the idea of E. M\"uller, the feedback between...
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...
Thermonuclear Supernovae: Is Deflagration Triggered by Floating Bubbles? (2002)
Bravo, Eduardo, Garcia-Senz, Domingo
In recent years, it has become clear from multidimensional simulations that the outcome of deflagrations depends strongly on the initial configuration of the flame. We have studied under which...
Influence of geometry in the delayed detonation model of SNIa (2002)
Garcia-Senz, Domingo, Bravo, Eduardo
We present several hydrodynamical simulations of thermonuclear supernovae dealing with multiple delayed detonations. The calculations were carried out in three dimensions, making possible to study...

Garcia-Senz, Domingo, Bravo, Eduardo
The explosion of a white dwarf of mass 1.36 M$_\odot$ has been simulated in three dimensions with the aid of a SPH code. The explosion follows the delayed detonation paradigma. In this case the...
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...
