Article
Accés restringit per política de l'editorialA type Ia supernova is thought to be a thermonuclear explosion of either a single carbon–oxygen white dwarf or a pair of merging white dwarfs. The explosion fuses a large amount of radioactive 56Ni. After the explosion, ... -
Collision of detonation waves and its implications in the nucleosynthesis of Type Ia supernovae

Article
Accés restringit per política de l'editorialWith currently known input physics and computer simulations in one dimension, a self-consistent treatment of core-collapse supernovae does not yet lead to successful explosions, while two-dimensional models show some ... -
Computer simulations using implicit Lagrangian hydrodynamics in 3D
Escartín Vigo, José Antonio; García Senz, Domingo; Bravo Guil, Eduardo (2011)
Comunicació de congrés
Accés obertThe method known as Smoothed Particle Hydrodynamics (SPH) is an important tool in modern numerical Astrophysics. It has been extensively used to simulate a large number of systems ranging from planets to clusters of ... -
Consequences of the Collision Between the Gas Ejected in the Collapse of a White Dwarf and a Low-Mass Star

Constraining deflagration models of type Ia supernovae through intermediate-mass elements
García Senz, Domingo; Bravo Guil, Eduardo; Cabezón Gómez, Rubén Martín; Woosley, S E (2007-05)
Article
Accés restringit per política de l'editorialThe physical structure of a nuclear flame is a basic ingredient of the theory of Type Ia supernovae (SNe Ia). Assuming an exponential density reduction with several characteristic times, we have followed the evolution of ... -
Constraints on the physics of type Ia supernovae from the X-ray spectrum of the Tycho supernova remnant
Badenes Montoliu, Carles; Borkowski, K.J.; Hughes, J.P.; Hwang, U.; Bravo Guil, Eduardo (2006-07)
Article
Accés restringit per política de l'editorialWe 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 progenitors in the ... -
Coulomb corrections to the equation of state of nuclear statistical equilibrium matter: implications for SNIa nucleosynthesis and the accretion-induced collapse of white dwarfs
Bravo Guil, Eduardo; García Senz, Domingo (1999-08)
Article
Accés obertCoulomb corrections to the equation of state of degenerate matter are usually neglected in high-temperature regimes, owing to the inverse dependence of the plasma coupling constant, G, on temperature. However, nuclear ... -
