Electromagnetic energy loss of axion stars
نویسندگان
چکیده
The rate of energy exchange spatially localized and gravitationally bound axion configurations with electromagnetic radiation is investigated in the presence strong static magnetic fields. A fully analytic treatment achieved based on variationally optimized separable spatiotemporal clump profiles. For dilute stars equation variation reinterpreted as a number. Its solutions hints at an asymptotic $\ensuremath{\sim}{t}^{1/5}$ increase size.

Axion miniclusters and Bose stars.
Evolution of inhomogeneities in the axion field around the QCD epoch is studied numerically, including for the first time important nonlinear effects. It is found that perturbations on scales corresponding to causally disconnected regions at T ∼ 1GeV can lead to very dense axion clumps, with present density ρa > ∼ 10 g cm. This is high enough for the collisional 2a → 2a process to lead to Bose–...
متن کاملmagnetized degenerate stars cooling by axion emission ?
We considered recently as a new axion production mechanism the process e − → e − +a in a strong magnetic field B. Requiring that for a strongly magnetized neutron star the axion luminosity is smaller than the neutrino luminosity we obtained the bound g ae < ∼ 10 −10 for the axion electron coupling constant. This limit is considerably weaker than the bound derived earlier by Borisov and Grishina...
متن کاملElectromagnetic Catalysis of the Radiative Decay of the Axion
The radiative decay of the axion a → γγ is investigated in an external electromagnetic field in DFSZ model in which axion couples to both quarks and leptons at tree level. The decay probability is strongly catalyzed by the external field, namely, the field removes the main suppression caused by the smallness of the axion mass. will be published in Phys. Lett. B Various extensions of the Standar...
متن کاملElectromagnetic Emission and Energy Loss in the QGP
I discuss why photon production from the Quark Gluon Plasma (QGP) presents an interesting problem, both experimentally and theoretically. I show how the photon emission rate can be computed under the simplifying assumption that the QGP fully thermalizes. The theoretical issues are very similar to those for jet energy loss; so it should be possible to treat them in a common formalism and relate ...
متن کاملAxion Decay of a Photon in an External Electromagnetic Field
An interaction of a pseudoscalar particle with two photons induced by an external electromagnetic field is used to study the photon decay γ → γa where a is a pseudoscalar particle associated with the Peccei-Quinn U(1) symmetry. The fieldinduced axion emission by photon is analyzed as a possible source of energy losses by astrophysical objects.
