Descripción
It has been shown that the shape of the luminosity function of white dwarfs (WDLF) is a powerful tool to check for the possible existence of DFSZ-axions, a proposed but not yet detected type of weakly interacting particles. With the aim of deriving new constraints on the axion mass, we compute in this paper new theoretical WDLFs on the basis of WD evolving models that incorporate the feedback of axions on the thermal structure of the white dwarf. We find that the impact of the axion emission into the neutrino emission cannot be neglected at high luminosities (M_{bol}< 8) and that the axion emission needs to be incorporated self-consistently into the evolution of the white dwarfs when dealing with axion masses larger than m_{a} cos^2{eta} > 5 meV (i.e. axion-electron coupling constant g_{ae}> 1.4× 10^{-13}). We went beyond previous works by including 5 different derivations of the WDLF in our analysis. Then we have performed chi^2-tests to have a quantitative measure of the agreement between the theoretical WDLFs ? computed under the assumptions of different axion masses and normalization methods --- and the observed WDLFs of the Galactic disk. While all the WDLF studied in this work disfavour axion masses in the range suggested by asteroseismology m_{a} cos^2{eta}> 10 meV; g_{ae}> 2.8× 10^{-13}) lower axion masses cannot be discarded from our current knowledge of the WDLF of the Galactic Disk. A larger set of completely independent derivations of the WDLF of the galactic disk as well as a detailed study of the uncertainties of the theoretical WDLFs is needed before quantitative constraints on the axion-electron coupling constant can be made.
