Accés obertContext. SN2011fe was detected by the Palomar Transient Factory in M101 on August 24, 2011, a few hours after the explosion. From the early optical spectra it was immediately realized that it was a Type Ia supernova, thus ... -
Observational evidence for high neutronization in supernova remnants : implications for type Ia supernova progenitors
Martinez Rodriguez, Hector; Badenes Montoliu, Carles; Yamaguchi, H; Bravo Guil, Eduardo; Timmes, Frank; Miles, Broxton; Townsley, Dean; Piro, Anthony; Mori, Hideyuki; Andrews, Brett; Park, Sangwook (2017-06-28)
Article
Accés obertThe physical process whereby a carbon–oxygen white dwarf explodes as a Type Ia supernova (SN Ia) remains highly uncertain. The degree of neutronization in SN Ia ejecta holds clues to this process because it depends on the ... -

Secondary fe-peak nuclei in the tycho supernova remnant
Badenes Montoliu, Carles; Bravo Guil, Eduardo; Hughes, J.P. (2008)
Comunicació de congrés
Accés obertThe 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 obertCurrent 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'editorialWe 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 ... -
