The evolution of white dwarfs is essentially a cooling process that depends primarily on the energy stored in their degenerate cores and on the transparency of their envelopes. In this paper we compute accurate cooling sequences for carbon-oxygen white dwarfs with hydrogen dominated atmospheres for the full range of masses of interest. For this purpose we use the most accurate available physical inputs for both the equation of state and opacities of the envelope and for the thermodynamic…

New cooling sequences for old white dwarfs
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
Outer boundary conditions for evolving cool white dwarfs
White dwarf evolution is essentially a gravothermal cooling process, which,for cool white dwarfs, sensitively depends on the treatment of the outer boundary conditions. We provide detailed outer
Latest generation white dwarf cooling models : theory and applications
White dwarfs are the most common stellar evolutionary end-point. Moreover, they can be considered as reliable cosmic clocks to infer the age of a wide variety of stellar populations, including
White Dwarf cooling Sequences, II: luminosity functions
Context. Given the importance of white dwarfs (WDs) in many fields of modern astrophysics, the precise knowledge of the actual degree of accuracy of the associated theoretical predictions is a
New phase diagrams for dense carbon-oxygen mixtures and white dwarf evolution
Context. Cool white dwarfs are reliable and independent stellar chronometers. The most common white dwarfs have carbon-oxygen dense cores. Consequently, the cooling ages of very cool white dwarfs
The age and colors of massive white dwarf stars
We present evolutionary calculations and colors for massive white dwarfs with oxygen-neon cores for masses between 1.06 and 1.28 Mo. The evolutionary stages computed cover the luminosity range from
The contribution of oxygen-neon white dwarfs to the MACHO content of the Galactic halo
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
Calibration of White Dwarf Cooling Sequences: Theoretical Uncertainty
White dwarf luminosities are powerful age indicators, whose calibration should be based on reliable models. We discuss the uncertainty of some chemical and physical parameters and their influence on
The spectral distribution of field white dwarfs shows a feature called the "non-DA gap." As defined by Bergeron et al., this is a temperature range (5100-6100 K) where relatively few non-DA stars are
Gravitational Settling of 22Ne and White Dwarf Evolution
We study the effects of the sedimentation of the trace element 22Ne in the cooling of white dwarfs. In contrast with previous studies—which adopted a simplified treatment of the effects of 22Ne


The Cooling of CO White Dwarfs: Influence of the Internal Chemical Distribution
White dwarfs are the remnants of stars of low and intermediate masses on the main sequence. Since they have exhausted all of their nuclear fuel, their evolution is just a gravothermal process. The
Pure Hydrogen Model Atmospheres for Very Cool White Dwarfs
Microlensing events observed in the line of sight toward the LMC indicate that a significant fraction of the mass of the dark halo of the Galaxy is probably composed of white dwarfs. In addition,
Properties of high-density binary mixtures and the age of the Universe from white dwarf stars
The luminosity of white dwarf stars can be attributed to the cooling process of their degenerate cores. The simple relationship existing between their luminosity and their age, together with the lack

In this study we compute the structure and evolution of carbon-oxygen DA white dwarfs by means of a detailed and updated evolutionary code. We treat the energy transport by convection within the

We present new white dwarf cooling models that incorporate an accurate outer boundary condition based on new opacity and detailed radiative transfer calculations. We —nd that helium-atmosphere dwarfs
The energetics of crystallizing white dwarfs revisited again
The evolution of white dwarfs is a cooling process that depends on the energy stored in the core and on the way in which it is transferred through the envelope. In this paper we show that despite

Old and blue white-dwarf stars as a detectable source of microlensing events
The analysis of gravitational microlensing events of stars, in the Large Magellanic Cloud places the masses of the lensing objects in the range 0.3–0.8 solar masses, suggesting that they might be old
The Physics of Crystallizing White Dwarfs
White dwarfs can be used as Galactic chronometers and, therefore, provide important information about Galactic evolution if good theoretical models of their cooling are available. Consequently, it is
