Recent measurements by Hipparcos present observational evidence supporting the existence of some white dwarf (WD) stars with iron-rich core composition. In connection with this, the present paper is aimed at exploring the structure and evolution of iron-core WDs by means of a detailed and updated evolutionary code. In particular, we examined the evolution of the central conditions, neutrino luminosity, surface gravity, crystallization, internal luminosity profile and ages. We find that the… Expand
The white dwarf luminosity function
White dwarfs are the final remnants of low- and intermediate-mass stars. Their evolution is essentially a cooling process that lasts for $\sim 10$ Gyr. Their observed properties provide informationExpand
Testing the initial-final mass relationship of white dwarfs
In this contribution we revisit the initial-final mass relationship of white dwarfs, which links the mass of a white dwarf with that of its progenitor in the main-sequence. Although this function isExpand
On the possibility of using seismic probes to study the core composition in pulsating white dwarfs
White dwarfs correspond to the final stages of stellar evolution of solar-type stars. In these objects, production of energy by nuclear burning has ended which means that a white dwarf simply coolsExpand
WD0433+270: an old Hyades stream member or an Fe-core white dwarf?
Context. G39-27/289 is a common proper-motion pair formed by a white dwarf (WD0433+270) and a main-sequence star (BD+26 730) that apparently has been classified as a member of the Hyades openExpand
Black dwarf supernova in the far future
In the far future long after star formation has ceased the universe will be populated by sparse degenerate remnants, mostly white dwarfs, though their ultimate fate is an open question. These whiteExpand
Hot degenerate dwarfs in a two-phase model
The characteristics of degenerate dwarfs-core radius, mass, and energy, thickness of their outer layers-are calculated based on a mechanical-equilibrium equation in a five-parameter, two-phaseExpand
Host Galaxy Effects in the Susy Model for Supernovae Ia
For more than forty years virtually all work on the theory of type Ia Supernovae (SN Ia) has assumed that these explosions were due to the transfer of mass to a degenerate star from a partner in aExpand
We propose a simple model explaining two outstanding astrophysical problems related to compact objects: (1) that of stars such as G87–7 (alias EG 50) that constitute a class of relatively low-massExpand
Constraining the Evolution of ZZ Ceti
We report our analysis of the stability of pulsation periods in the DAV star (pulsating hydrogen atmosphere white dwarf) ZZ Ceti, also called R548. On the basis of observations that span 31 years, weExpand
Astrophysics in 2000
It was a year in which some topics selected themselves as important through the sheer numbers of papers published. These include the connection(s) between galaxies with active central engines andExpand


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. TheExpand
The fastest evolving white dwarfs
The evolution of white dwarfs (WDs) at their lowest luminosities is investigated by computing a reference track with solar metal and helium abundances down to the beginning of WD evolution. The mainExpand
Evolution of Helium White Dwarfs of Low and Intermediate Masses
We present detailed calculations of the evolution of low-mass, helium white dwarf models with masses from M = 0.1 to M = 0.5 M? at intervals of 0.05 M? and with a metallicity of Z = 10-3. For thisExpand
Effects of Fe/C phase separation on the ages of white dwarfs
The energy release associated with the phase separation of Fe from C in a predominantly C white dwarf is calculated. The total gravitational-plus-internal energy differences between models ofExpand
The Cool White Dwarf Luminosity Function and the Age of the Galactic Disk
We present new optical and infrared data for the cool white dwarfs in the proper motion sample of Liebert, Dahn, & Monet. Stellar properties—surface chemical composition, effective temperature,Expand
Evolution of DA white dwarfs in the context of a new theory of convection
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 theExpand
We present an analysis of the evolution of carbon-oxygen DB white dwarfs (helium­ rich envelope) for a wide range of effective temperatures and luminosities. To this end, we employ a full stellarExpand
Testing the White Dwarf Mass-Radius Relation with Hipparcos*
We present the Hipparcos parallaxes and resulting radii for 10 white dwarfs in visual binaries or common proper-motion systems and 11 field white dwarfs. For bright stars, Hipparcos parallaxes haveExpand
The outcome of explosive ignition of ONeMg cores: supernovae, neutron stars, or iron white dwarfs?
Models are used to explore the outcome of explosive ignition of ONeMg cores, which result from the evolution of stars in a mass range between 8 and 10 solar masses. Arguments are presented showingExpand
An Introduction to the Study of Stellar Structure
EDDINGTON'S “Internal Constitution of the Stars” was published in 1926 and gives what now ranks as a classical account of his own researches and of the general state of the theory at that time. SinceExpand
