Abstract: |
Recent determinations of the white dwarf luminosity function (WDLF) from very
large surveys have extended our knowledge of the WDLF to very high
luminosities. It has been shown that the shape of the luminosity function of
white dwarfs (WDLF) is a powerful tool to test the possible properties and
existence of fundamental weakly interacting subelectronvolt particles. This,
together with the availability of new full evolutionary white dwarf models
that are reliable at high luminosities, have opened the possibility of testing
particle emission in the core of very hot white dwarfs. We use the available
WDLFs from the Sloan Digital Sky Survey and the SuperCOSMOS Sky Survey to
constrain the values of the neutrino magnetic dipole moment (μν) and
the axion-electron coupling constant (gae) of DFSZ-axions. |
