Polarimetric effects related with discovering Goldstone bosons in stars and galaxies.
Abstract
Polarimetric methods are proposed for searching light Goldstone bosons (axions and arions) in the emission of astronomic objects. The main idea involves using the photon-to-Goldstone boson conversion process in magnetic fields of compact stars and also of interstar and intergalaxy media. Such a process depends strongly on the state of the photon polarization and may result in arising of a noticeable emission polarization. The polarimetric observations may give strong restrictions for the Goldstone boson-photon coupling constant. Radiopulsars, X-ray double systems with small massive components and magnetic white dwarfs are the best representatives for observation. For the interstar medium, the effect may be comparable with the interstar polarization. The emission flows from quasars and nuclei of the active galaxies may oscillate as a function of the cosmological redshift due to the effect of the photon-arion conversion.
