Galaxy’s brightest gamma-ray binary system may be powered by a magnetar

An impression of the gamma-ray binary system LS 5039. A neutron star (left) and its massive, companion star (right). The research team suggests that the neutron star at the heart of LS 5039 has an ultra-strong magnetic field, and is arguably a magnetar. The field accelerates high-energy particles inside the bow-shaped region, thereby emitting gamma-rays […]
