Abstract Axion stars are hypothetical objects formed of axions, obtained as localized and coherently oscillating solutions to their classical equation of motion. Depending on the value of the field amplitude at the core | θ 0 | ≡ | θ ( r = 0 ) | , the equilibrium of the system arises from the balance of the kinetic pressure and either self-gravity or axion self-interactions. Starting from a general relativistic framework, we obtain the set of equations describing the configuration of the axion… Expand

Dense Axion Stars.
TLDR
A new branch of dense axion stars is found in which gravity is balanced by the mean-field pressure of the axion Bose-Einstein condensate, and this branch could produce a bosenova, leaving a dense axions star as the remnant. Expand
Collapse of axion stars

TLDR
It is found that axion perturbations on scales corresponding to causally disconnected regions at [ital T][similar to]1 GeV can lead to very dense pseudosoliton configurations the authors call axitons, which evolve to axion miniclusters with a present density high enough to lead to Bose-Einstein relaxation in the gravitationally bound clumps of axions, forming Bose stars.

Calculation of the axion mass based on high-temperature lattice quantum chromodynamics
TLDR
This work determines the axion mass using lattice QCD, assuming that these particles are the dominant component of dark matter, and determines the universal axionic angle that corresponds to the initial condition of the authors' Universe. Expand
