Axion stars in MGD background

چکیده

The minimal geometric deformation (MGD) paradigm is here employed to survey axion stars on fluid branes. finite value of the brane tension provides beyond-general relativity corrections density, compactness, radius, and asymptotic limit gravitational mass function stars, in a MGD background. also enhances effective range magnitude field coupled gravity. are compatible mini-massive compact halo objects for almost all observational tension, however, narrow allows star densities large enough produce stimulated decays photons, with no analogy general-relativistic (GR) limit. Besides, density shown be up four orders larger than GR being less sensitive tidal disruption events under collision neutron lower values tension.

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–...

magnetized 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...

Detecting stars beyond the background noise level

It is possible to extract the number of stars per magnitude interval (luminosity function) from the histogram of a crowded stellar field image if the point spread function is known sufficiently well. There are no severe uniqueness problems with the solution. The method is sensitive to errors in the point spread function, but the shape of the luminosity function plays a role as well. Further wor...

Axion-photon couplings in invisible axion models.

We reexamine the axion-photon couplings in various invisible axion models motivated by the recent proposal of using optical interferometry at the ASST facility in the SSCL to search for axion. We illustrate that the assignment of U(1)PQ charges for the fermion fields plays an important role in determining the couplings. Several simple non-minimal invisible axion models with suppressed and enhan...

QCD Axion and Quintessential Axion

The axion solution of the strong CP problem is reviewed together with the other strong CP solutions. We also point out the quintessential axion(quintaxion) whose potential can be extremely flat due to the tiny ratio of the hidden sector quark mass and the intermediate hidden sector scale. The quintaxion candidates are supposed to be the string theory axions, the model independent or the model d...
