Physicists show that neutron stars may be covered in axion clouds
Axion cloud around a neutron star. Although some axions escape the star’s gravity, many remain bound to the star and form clouds that surround it for long periods of time. Interaction with the neutron star’s strong magnetic field converts some axions into photons, or light that can eventually be detected by telescopes on Earth. Credit: University of Amsterdam A team…
