Im renommierten Fachblatt Physical Review Letters ist gerade ein Papier erschienen, welches eine bereits von anderen Autoren berichtete Anomalie im Röntgenspektrum zweier Neutronensterne als möglichen Hinweis auf Axionen deutet:
Axion Emission Can Explain a New Hard X-Ray Excess from Nearby Isolated Neutron Stars
Hard X-Ray Excess From The Magnificent Seven Neutron Stars
Die Objekte gehören zu einer Sammlung naher und besonders gut untersuchter Neutronensternen mit dem informellen Namen The Magnificent Seven
Axions may be produced thermally inside the cores of neutron stars (NSs), escape the stars due to their feeble interactions with matter, and subsequently convert into x rays in the magnetic fields surrounding the stars. We show that a recently discovered excess of hard x-ray emission in the 2–8 keV energy range from the nearby magnificent seven isolated NSs could be explained by this emission mechanism. We show that the hard x-ray excess may be consistently explained by an axionlike particle with mass m_a ≲ 2 × 10−5 eV ...
X-rays surrounding 'Magnificent 7' may be traces of sought-after particle
