The contribution of oxygen-neon white dwarfs to the MACHO content of the Galactic halo
(2007-06-13)
Article.
Accés obert
Article.
Accés obert
Context. The interpretation of microlensing results towards the Large Magellanic Cloud (LMC) still remains controversial. White
dwarfs have been proposed to explain these results and, hence, to contribute significantly ...
Constraining the double-degenerate scenario for Type Ia supernovae from merger ejected matter
(2015-03-01)
Article.
Accés obert
Article.
Accés obert
We follow the mass expelled during the WD-WD merger process in a particular case of the double-degenerate (DD) scenario for Type Ia supernovae (SNe Ia), and find that the interaction of the SN ejecta with the resulting ...
Detonations in white dwarf dynamical interactions
(2013)
Article.
Accés obert
Article.
Accés obert
n 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 ...

We present full evolutionary calculations appropriate for the study of hydrogen-rich DA white dwarfs. This is
done by evolving white dwarf progenitors from the zero-age main sequence, through the core hydrogen-burning
phase, ...
White dwarfs as astroparticle physics laboratories
(European Astronomical Society, 2007)
Article.
Accés obert
Article.
Accés obert
White dwarfs are well studied objects. The relative simplic-
ity of their physics allows to obtain very detailed models which can
be ultimately compared with their observed properties. Among them
there is a specific ...
Recent advances in the modelling of classical novae and type I X-ray bursts
(2012)
Article.
Accés obert
Article.
Accés obert
Classical nova outbursts and type I X-ray bursts are thermonuclear stellar explosions driven by charged-particle reactions. Extensive numerical simulations of nova explosions have shown that the accreted envelopes attain ...
The white dwarf luminosity function II. The efect of the measurement errors and other biases
(Royal Astronomical Society, 2007-09)
Article.
Accés obert
Article.
Accés obert
The disc white dwarf luminosity function is an important tool for studying the solar neighbourhood, since it allows the determination of several Galactic parameters, the most important one being the age of the Galactic ...
A population synthesis study of the luminosity function of hot white dwarfs
(2014-03-05)
Article.
Accés obert
Article.
Accés obert
Context. We present a coherent and detailed Monte Carlo simulation of the population of hot white dwarfs. We assess the statistical significance of the hot end of the white dwarf luminosity function and the role played by ...
Seismological constraints on the high-gravity DOV stars PG 2131+066 and PG 1707+427

Article.
Accés restringit per política de l'editorial
A seismological study of the pulsating PG1159 stars PG2131+066 and PG 1707+427 is presented. We perform extensive adiabatic computations of g-mode pulsation periods of PG1159 evolutionary models with stellar masses ranging ...
High-resolution smoothed particle hydrodynamics simulations of the merger of binary white dwarfs
(2009-06)
Article.
Accés obert
Article.
Accés obert
Context. The coalescence of two white dwarfs is the final outcome of a sizeable fraction of binary stellar systems. Moreover, this
process has been proposed to explain several interesting astrophysical phenomena.
