Axion emission by hot and dense plasmas is a new energy-loss channel for stars. Observable consequences include a modification of the solar sound-speed profile, an increase of the solar neutrino flux, a reduction of the helium-burning lifetime of globular-cluster stars, accelerated white-dwarf cooling, and a reduction of the supernova SN 1987A neutrino burst duration. I review and update these arguments and summarize the resulting axion constraints. 

Journey at the axion meV mass frontier

The cooling speed of white dwarfs suggests a possible new energy-loss channel, consistent with axions if their Yukawa coupling to electrons is 10−13 corresponding to a mass of a few meV. In this case

Decay photons from the axionlike particles burst of type II supernovae

We determine limits from SN 1987A on massive axion-like particles (ALPs) with masses in the 10 keV - 100 MeV range and purely coupled to two photons. ALPs produced in the core collapse escape from

Cosmological bounds on sub-MeV mass axions

Axions with mass ma ≳ 0.7 eV are excluded by cosmological precision data because they provide too much hot dark matter. While for ma ≳ 20 eV the a → 2γ lifetime drops below the age of the universe,

Heavy axion-like particles and core-collapse supernovae: constraints and impact on the explosion mechanism

Heavy axion-like particles (ALPs), with masses ma ≳ 100 keV, coupled with photons, would be copiously produced in a supernova (SN) core via Primakoff process and photon coalescence. Using a

Solar neutrino limit on axions and keV-mass bosons

The all-flavor solar neutrino flux measured by the Sudbury Neutrino Observatory constrains nonstandard energy losses to less than about 10% of the Sun's photon luminosity, superseding a

Constraints on Axion-Lepton coupling from Big Bang Nucleosynthesis

In this article, we study the implications of the coupling between Axion-Like-Particles (ALPs) and Leptons to cosmology in particular, the Big Bang Nucleosynthesis (BBN) . We show that the BBN,

Constraining the axion-photon coupling with massive stars.

It is pointed out that stars in the mass window ~8-12M([circumpunct]) can serve as sensitive probes of the axion-photon interaction, g(Aγγ), and conservatively finds g( Aγγ)</~0.8×10(-10) GeV(-1), which compares favorably with the existing bounds.

Axion constraints from white dwarf cooling times

Axions and SN 1987A.

It is found that for an axion mass of greater than approx.10/sup -3/ eV, axion emission shortens the duration of the expected neutrino burst so significantly that it would be inconsistent with the neutrinos observations made by the Kamiokande II and Irvine-Michigan-Brookhaven detectors.

Asymptotic giant branch stars as astroparticle laboratories

We show that the inclusion of axion emission during stellar evolution introduces important changes into the evolutionary behaviour of aymptotic giant branch (AGB) stars. The mass of the resulting C/O

Astrophysical Bounds on the Masses of Axions and Higgs Particles

Lower bounds on the mass of a light scalar (Higgs) or pseudoscalar (axion) particle are found in three ways* (1) by requiring that their effect on primordial nucleosynthesis not yield a deuterium

The cooling of hot white dwarfs: a theory with non-standard weak interactions, and a comparison with observations

We present calculations of the cooling evolutionary sequences of hot (T eff >12×10 3 K) white dwarf stars. The input physics is discussed in some detail, with special emphasis on the thermal

A Fresh Look at Axions and SN 1987A

We re-examine the very stringent limits on the axion mass based on the strength and duration of the neutrino signal from SN 1987A, in the light of new measurements of the axial-vector coupling
