Axions and the white dwarf luminosity function
J. Isern, S. Catalan, E. Garcia-Berro +1
The evolution of white dwarfs can be described as a simple cooling process. Recently, it has been possible to determine with an unprecedented precision their luminosity function, t…
Axions and the cooling of white dwarf stars
J. Isern, E. Garcia-Berro, S. Torres +1
White dwarfs are the end-product of the lifes of intermediate- and low-mass stars and their evolution is described as a simple cooling process. Recently, it has been possible to de…
The initial-final mass relationship of white dwarfs revisited: effect on the luminosity function and mass distribution
S. Catalan, J. Isern, E. Garcia-Berro +1
The initial-final mass relationship connects the mass of a white dwarf with the mass of its progenitor in the main-sequence. Although this function is of fundamental importance to…
The contribution of red dwarfs and white dwarfs to the halo dark matter
S. Torres, J. Camacho, J. Isern +1
The nature of the several microlensing events observed by the MACHO team towards the LMC still remains controversial. Low-mass substellar objects and stars with masses larger than…
The contribution of Oxygen-Neon white dwarfs to the MACHO content of the Galactic Halo
J. Camacho, S. Torres, J. Isern +2
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…
The white dwarf luminosity function --II. The effect of the measurement errors and other biases
S. Torres, E. Garcia-Berro, J. Isern
Only the 1/V_max method has been employed so far for observationally determining the white dwarf luminosity function, whereas for other kind of luminosity functions several other m…
