Metallicity as a Source of Dispersion in the SNIa Bolometric Light Curve Luminosity-width Relationship
Bravo Guil, Eduardo; Domínguez, Inmaculada; Badenes Montoliu, Carles; Piersanti, Luciano; Straniero, Oscar (2010-02-18)
Article
Accés restringit per política de l'editorialThe recognition that the metallicity of Type Ia supernova (SNIa) progenitors might bias their use for cosmological applications has led to an increasing interest in its role in shaping SNIa light curves. We explore the ... -
Observation of SN2011fe with INTEGRAL - I : pre-maximum phase
Isern Vilaboy, Jordi; Jean, Pierre; Bravo Guil, Eduardo; Diehl, Roland; Knödlseder, Jurgen; Domingo, A.; Hirschmann, Alina; Hoeflich, Peter; Lebrun, F.; Renaud, M.; Soldi, Simona; Elias-Rosa, Nancy; Hernanz Carbó, Margarita; Kulebi, Baybar; Zhang, X.; Badenes Montoliu, Carles; Domínguez, Inmaculada; García Senz, Domingo; Jordi, Carme; Lichti, G.; Vedrenne, G.; von Ballmoos, Peter (2013-04)
Article
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 ... -
On the internal composition of white dwarfs
Isern Vilaboy, Jordi; Bravo Guil, Eduardo; García-Berro Montilla, Enrique; Domínguez, Inmaculada; Salaris, M. (2001-05)
Article
Accés restringit per política de l'editorial -
On the photometric homogeneity of type IA supernovae
Bravo Guil, Eduardo; Domínguez, Inmaculada; Isern Vilaboy, Jordi; Canal Corretger, Ramon; Höflich, P.; Labay, Javier (1993-03)
Article
Accés obertThe dependence of the characteristics of the light curves of Type Ia supernovae on the ignition density of the progenitor white dwarf is studied with the aid of two models of propagation of the thermonuclear burning front: ... -
Pulsating reverse detonation models of Type Ia supernovae. II. Explosion
Bravo Guil, Eduardo; García Senz, Domingo; Cabezón Gómez, Rubén Martín; Domínguez, Inmaculada (2009-04)
Article
Accés restringit per política de l'editorialObservational evidences point to a common explosion mechanism of Type Ia supernovae based on a delayed detonation of a white dwarf (WD). However, all attempts to find a convincing ignition mechanism based on a delayed ... -
Rotating type Ia SN progenitors: explosion and light curves
Domínguez, Inmaculada; Piersanti, L.; Bravo Guil, Eduardo; Tornambé, A.; Straniero, O.; Gagliardi, S. (2006-06)
Article
Accés restringit per política de l'editorialBased on the rigidly rotating progenitor models found to be able to grow up to the canonical Chandrasekhar mass limit and beyond, and undergo a thermonuclear explosion, we compute the explosions, detailed nucleosynthesis, ... -
Supernovae and dark energy
Domínguez, Inmaculada; Bravo Guil, Eduardo; Piersanti, Luciano; Straniero, Oscar; Tornambé, Amedeo (Astronomical Society of the Pacific, 2008)
Text en actes de congrés
Accés obertA decade ago the observations of thermonuclear supernovae at high-redhifts showed that the expansion rate of the Universe is accelerating and since then, the evidence for cosmic acceleration has gotten stronger. This ... -
The elusive nature of the r-stars
Domínguez, Inmaculada; Piersanti, Luciano; Cabezón Gómez, Rubén Martín; Zamora, O.; García Senz, Domingo; Abia, C.; Straniero, Oscar (2010-10-10)
Article
Accés obertR stars are carbon stars, less luminous and hotter than the carbon stars evolving along the AGB phase. Thus, their carbon enrichment cannot be a consequence of the third dredge-up, a fact also in agreement with the lack ... -
The fate of CO white dwarfs that experience slow deflagrations
Bravo Guil, Eduardo; Domínguez, Inmaculada; Isern Vilaboy, Jordi (1999-10)
Article
Accés obertIt has been suggested that the differences among the observational Type Ia supernovae (SNIa) set can be accounted for by invoking two regimes of propagation of combustion. Normal SNIa should be produced by rapid deflagrations ... -
The impact of chemical differentiation of white dwarfs on thermonuclear supernovae
Bravo Guil, Eduardo; Althaus, Leandro Gabriel; García-Berro Montilla, Enrique; Domínguez, Inmaculada (2010-12-16)
Article
Accés obertAims. Gravitational settling of 22Ne in cooling white dwarfs can affect the outcome of thermonuclear supernovae. We investigate how the supernova energetics and nucleosynthesis are in turn influenced by this process. We ... -
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'editorialThe 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 ... -
Type Ia supernovae and the 12C+12C reaction rate
Bravo Guil, Eduardo; Piersanti, Luciano; Domínguez, Inmaculada; Straniero, Oscar; Isern Vilaboy, Jordi; Escartín Vigo, José Antonio (2011-11-22)
Article
Accés obertContext. Even if the 12C+12C reaction plays a central role in the ignition of type Ia supernovae (SNIa), the experimental determination of its cross-section at astrophysically relevant energies (E ≲ 2 MeV) has never been ... -
Type Ia supernovae: Can Coriolis force break the symmetry of the gravitational confined detonation explosion mechanism?
García Senz, Domingo; Cabezón, Rubén Martin; Domínguez, Inmaculada; Thielemann, Friedrich-K (Institute of Physics (IOP), 2016-03-10)
Article
Accés obert© 2016. The American Astronomical Society. All rights reserved.. Currently the number of models aimed at explaining the phenomena of type Ia supernovae is high and distinguishing between them is a must. In this work we ...
