    • Secondary fe-peak nuclei in the tycho supernova remnant 

      Badenes Montoliu, Carles; Bravo Guil, Eduardo; Hughes, J.P. (2008)
      Comunicació de congrés
      Accés obert
      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 them in the framework ...

    • SNR-calibrated Type Ia supernova models 

      Bravo Guil, Eduardo; Badenes Montoliu, Carles; Martinez Rodriguez, Hector (Oxford University Press, 2019-02)
      Article
      Accés obert
      Current Type Ia supernova (SN Ia) models can reproduce most visible+IR + UV observations. In the X-ray band, the determination of elemental abundance ratios in supernova remnants (SNRs) through their spectra has reached ...

    • The end of amnesia: A new method for measuring the metallicity of Type Ia supernova progenitors using manganese lines in supernova remnants 

      Badenes Montoliu, Carles; Bravo Guil, Eduardo; Hughes, J.P. (2008-06)
      Article
      Accés restringit per política de l'editorial
      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 Type Ia supernova ejecta ...

    • The imprint of presupernova evolution on supernova remnants 

      Badenes Montoliu, Carles; Bravo Guil, Eduardo (IOP PUBLISHING LTD, 2001-07)
      Article
      Accés restringit per política de l'editorial
      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 from the binary in the ...

    • The origin of the iron-rich knot in Tycho's supernova remnant 

      Yamaguchi, H; Hughes, John P.; Badenes Montoliu, Carles; Bravo Guil, Eduardo; Seitenzahl, Ivo R.; Martinez Rodriguez, Hector; Park, Sangwook; Petre, Robert (2017-01-09)
      Article
      Accés obert
      X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta, offering unique insight into the nucleosynthesis in supernova explosions. Here we present detailed imaging and ...

    • The persistence of memory, or how the X-ray spectrum of SNR 0509-67.5 reveals the brightness of its parent Type Ia supernova 

      Badenes Montoliu, Carles; Hughes, J.P.; Cassam, G.; Bravo Guil, Eduardo (2008-06)
      Article
      Accés restringit per política de l'editorial
      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 to estimate the kinetic ...

    • Thermal X-ray emission from shocked ejecta in Type Ia supernova remnants. II. Parameters affecting the spectrum 

      Badenes Montoliu, Carles; Borkowski, K.J.; Bravo Guil, Eduardo (2005-05)
      Article
      Accés restringit per política de l'editorial
      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 use the X-ray spectra of ...

    • Thermal X-ray emission from shocked ejecta in Type Ia supernova remnants: Prospects for explosion mechanism identification 

      Badenes Montoliu, Carles; Bravo Guil, Eduardo; Borkowski, K.J.; Domínguez, Inmaculada (2003-08)
      Article
      Accés restringit per política de l'editorial
      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 ...

    • White dwarf dynamical interactions and fast optical transients 

      García-Berro Montilla, Enrique; Badenes Montoliu, Carles; Aznar Siguan, Gabriela; Lorén Aguilar, Pablo (2017-07-01)
      Article
      Accés obert
      Recent advances in time-domain astronomy have uncovered a new class of optical transients with time-scales shorter than typical supernovae and a wide range of peak luminosities. Several subtypes have been identified within ...
