123-321 models of classical novae
(EDP Sciences, 2020-01-28)
Article
Open AccessContext. High-resolution spectroscopy has revealed large concentrations of CNO and sometimes other intermediate-mass elements (e.g., Ne, Na, Mg, or Al, for ONe novae) in the shells ejected during nova outbursts, suggesting ... -

8è Premi ex-aequo a la Qualitat de la Docència Universitària del Consell Social de la UPC: "La física a través de la Ciència-ficció"
(2006-02)
Conference report
Open AccessLa ciència-ficció, gènere característic del nostre temps, és una eina magnífica per a l’aprenentatge-ensenyament de la tecnociència, en general, i de la física, en particular. Els mites del gènere com ara King Kong, ... -
Absolute determination of the Na-22(rho, gamma)Mg-23 reaction rate in novae
(2011-03-23)
Article
Open AccessGamma-ray telescopes in orbit around the earth are searching for evidence of the elusive radionuclide 22Na produced in novae. Previously published uncertainties in the dominant destructive reaction, 22Na(p,γ)23Mg, indicated ... -
Application of the THM to the investigation of reactions induced by unstable nuclei: the 18F(p,a)15O case
(2019-12-04)
Article
Open AccessThe Trojan Horse Method is applied to the investigation of the18F(p,a)15O reaction, by extractingthe quasi free contribution to the2H(18F,a15O)nprocess. For the first time the method is applied to a reaction ofastrophysical ... -
A Trojan horse approach to the production of 18F in Novae
(2017-09-01)
Article
Open AccessCrucial information on nova nucleosynthesis can be potentially inferred from ¿-ray signals powered by 18F decay. Therefore, the reaction network producing and destroying this radioactive isotope has been extensively studied ... -

Classical and recurrent nova models
(2011)
Conference lecture
Open AccessRemarkable progress in the understanding of nova outbursts has been achieved through combined efforts in photometry, spectroscopy and numerical simulations. According to the thermonuclear runaway model, novae are powered ... -
Coordinated analysis of two graphite grains from the CO3.0 LAP 031117 meteorite: First identification of a CO Nova graphite and a presolar iron sulfide subgrain
(2016-07)
Article
Open AccessPresolar grains constitute remnants of stars that existed before the formation of the solar system. In addition to providing direct information on the materials from which the solar system formed, these grains provide ... -
Detonations in white dwarf dynamical interactions
(2013)
Article
Open Accessn old, dense stellar systems collisions of white dwarfs are a rather frequent phenomenon. Here we present the results of a comprehensive set of Smoothed Particle Hydrodynamics simulations of close encounters of white ... -

Experimentally well-constrained masses of 27P and 27S: implications for studies of explosive binary systems
(Elsevier, 2020-03-10)
Article
Open AccessThe mass of 27P is expected to impact the X-ray burst (XRB) model predictions of burst light curves and the composition of the burst ashes, but large uncertainties and inconsistencies still exist in the reported 27P masses. ... -
First measurement of the 34S(p,gamma)35Cl reaction rate through indirect methods for presolar nova grains
(AMER PHYSICAL SOC, 2017-08-02)
Article
Open AccessSulphur isotopic ratio measurements may help to establish the astrophysical sites in which certain presolar grains were formed. Nova model predictions of the 34S/32S ratio are, however, unreliable due to the lack of an ... -
