Description

Axions couple extremely weakly to regular matter, making them challenging to probe in the laboratory. However, axions should be produced in the hot and dense environments of compact stars, providing these stars with an additional cooling channel that leads to well-known constraints on the axion’s couplings to matter. These constraints are indirect, and although compact stars are predicted to “glow” in axions, this radiation is invisible to us. In this talk I will discuss how the axion radiation is converted into X-ray emission in the strong magnetic field that surround many compact stars, thereby providing a new strategy for probing axions through X-ray observations of white dwarfs and neutron stars.
