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…

First axion bounds from a pulsating helium-rich white dwarf star
The Peccei-Quinn mechanism proposed to solve the CP problem of Quantum Chromodynamics has as consequence the existence of axions, hypothetical weakly interacting particles whose mass is constrained
Stellar Recipes for Axion Hunters
There are a number of observational hints from astrophysics which point to the existence of stellar energy losses beyond the ones accounted for by neutrino emission. These excessive energy losses may
Constraining axion-like particles using the white dwarf initial-final mass relation
Axion-like particles (ALPs), a class of pseudoscalars common to many extensions of the Standard Model, have the capacity to drain energy from the interiors of stars. Consequently, stellar evolution
Axions and the Final Fate of Stars
Axions are weakly interactive bosons introduced to solve the longstanding CP problem. If their mass is small enough (up to a few keV), they can be produced in stellar interiors, and act as an
X-Ray Signatures of Axion Conversion in Magnetic White Dwarf Stars.
It is shown that the radiated axions may convert into x rays in the strong magnetic fields surrounding the WDs, leading to observable x-ray signatures, allowing for a definitive test of the axionlike-particle explanation of the stellar cooling anomalies.
Global fits of axion-like particles to XENON1T and astrophysical data
The excess of electron recoil events seen by the XENON1T experiment has been interpreted as a potential signal of axion-like particles (ALPs), either produced in the Sun, or constituting part of the
Axion global fits with Peccei-Quinn symmetry breaking before inflation using GAMBIT
A bstractWe present global fits of cosmologically stable axion-like particle and QCD axion models in the mass range 0.1 neV to 10 eV. We focus on the case where the Peccei-Quinn symmetry is broken
Stellar cooling anomalies and variant axion models
A number of observations of stellar systems show a mild preference for anomalously fast cooling compared with what predicted in the standard theory, which leads to a speculation that there exists an

Abstract The shape of the luminosity function of white dwarfs (WDLF) is sensitive to the characteristic cooling time and, therefore, it can be used to test the existence of additional sources or


Axions and the white dwarf luminosity function
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, that is, the number
An independent limit on the axion mass from the variable white dwarf star R548
Pulsating white dwarfs with hydrogen-rich atmospheres, also known as DAV stars, can be used as astrophysical laboratories to constrain the properties of fundamental particles like axions. Comparing
Axions and the pulsation periods of variable white dwarfs revisited
Axions are the natural consequence of the introduction of the Peccei-Quinn symmetry to solve the strong CP problem. All the efforts to detect such elusive particles have failed up to now.
White dwarfs as physics laboratories: the axion case
One of the tools for constraining the properties of some particles predicted by the different non-standard physical theories is the study of the evolutive properties of stars. The reason is that the

Particle-physics constraints from the globular cluster M5: neutrino dipole moments ?
Stellar evolution is modified if energy is lost in a “dark channel” similar to neutrino emission. Comparing modified stellar evolution sequences with observations provides some of the most

We demonstrate that plasmon neutrinos are the dominant form of energy loss in model white dwarf stars down to T_eff ~ 25,000 K, depending on the stellar mass. The lower end of this range overlaps the
