Outer boundary conditions for evolving cool white dwarfs
(EDP Sciences, 2012-10)
Context. White dwarf evolution is essentially a gravothermal cooling process, which, for cool white dwarfs, depends on the treatment of the outer boundary conditions. Aims. We provide detailed outer boundary conditions ...
Evolutionary and pulsational properties of low-mass white dwarf stars with oxygen cores resulting from close binary evolution
(Wiley Blackwell Publishing, Inc, 2004-01)
The present work is designed to explore the evolutionary and pulsational properties of low-mass white dwarfs with carbon/oxygen cores. In particular, we follow the evolution of a 0.33-M⊙ white dwarf remnant in a self-consistent ...
Complejidad o relativismo en Hayden WhiteComplexity or Relativism in Hayden White
(Universidad Nacional de Quilmes, 2015)
Las consideraciones de Hayden White en torno de la escritura histórica han tenido un fuerte impacto en la discusión contemporánea sobre la relación entre Historia y Verdad. El interés por los diversos niveles que forjan ...
Comparison of theoretical white dwarf cooling timescales.
(Edp Sciences S A, 2013-07)
Context. An accurate assessment of white dwarf cooling times is
paramount so that white dwarf cosmochronology of Galactic populations
can be put on more solid grounds. This issue is particularly relevant in
view of the ...
An upper limit to the secular variation of the gravitational constant from white dwarf stars
(Iop Publishing, 2011-05)
A variation of the gravitational constant over cosmological ages modifies the main sequence lifetimes and white dwarf cooling ages. Using an state-of-the-art stellar evolutionary code we compute the effects of a secularly ...
Mass distribution of DA white dwarfs in the First Data Release of the Sloan Digital Sky Survey
(EDP Sciences, 2004-12)
We investigate the sample of 1175 new nonmagnetic DA white dwarfs with the effective temperatures Teff ≥ 12 000 K, which were extracted from the Data Release 1 of the Sloan Digital Sky Survey. We determined masses, radii, ...
